I'm gone a lot. Sorry. ( Pilot life ) Have a hangar house with cables, steel door. Poplar Grove Airpark, airport designator C77... Would like a strap conversion because I saw your ad in General Aviation News. Approximate size of door is 42-43 feet across and 10-13 feet high. I'm not the first owner... Do you do the installation work? I'm not sure what information you need... I'm leaving today but should be back Monday, so if you wish to call me, next week should be good. If you get this in time, you might try me today before closing time... I might still be around. Thank you for your time.

This summer, our CAP unit is thinking about converting our 40-year-old cable lift for our 45 ft bifold hangar door to your strap conversion. Our Civil Air Patrol unit is on a very tight budget and might have to do some fundraising to accomplish our upgrade. Civil Air Patrol is an IRS-registered 501(c)(3) tax-exempt non-profit organization. Our Superior Wisconsin CAP unit membership has various talented members so we would like to do the conversion ourselves for budget reasons. So, first, we would like a quote to discuss at our bi-monthly meetings if we can even afford the project. As a 56-year member of our Superior Wisconsin Civil Air Patrol squadron, I have been involved with all of our CAP projects since the 1960s, including the many-many years of construction and upgrades to our existing hangar/meeting building. Our hangar frame is a 50 ft X 50 ft pole building. Our bi-fold door is 45 ft X 12 ft all steel. If we are able to proceed, we would like to order early to have everything in place by May 2023. Do you know of corporations willing to assist financially non-profit all volunteer organizations? I personally live in the winter months in Arizona and summer up north. Could you mail your information to me?

Looking to replace an existing bi-fold cable door from another company with a Liftstrap conversion. The current door does not open to the full 10'6". It opens to approximately 8" below the beam. Interested in all glass, but could also go with metal siding and windows.


We are looking to upgrade our existing steel bifold door to the Schweiss Lift strap and auto latch system. The physical door is 65ftX26ft and opens to 20ft. I do not know the weight of the door, but it's heavy enough to have me worrying about the safety of cables. I can provide pictures of the existing cable lift system. The current system has two lift motors and the drive tube is 2.5 inches in diameter.


I have a variety of hangar doors with cable-lift systems that I am considering replacing with much safer Schweiss strap-lift systems. I would like enough information to make an intelligent decision as to cost and benefits.


We have an Hi Fold Aircraft hanger door with with a cable lift system that has recently failed. the sixe of the bi-fold door is approximately 70' x 20'.I want to know if it can be converted to a strap system? the approximate cost?

Let me know what is needed or have someone call me so I can find out more information. Thanks mike

I am in the process of purchasing a hangar in Juneau, AK and the door is a concern. It is an old Wilson door, original equipment I believe from way long ago, probably early 70's. Door seems to be ok, sort of but it's cabled. Looking for options on new door vs strap conversion. Although I understand a strap conversion will also give me new motors. What would I need to give you in order to get an estimate on both? info below is rough dimensions at this point. Scott Harris

At the Springdale Municipal Airport, we have three hangars with large, bi-fold cable doors. I am curious to know if lift straps would be an affordable replacement for our current system that seems to need constant replacement of cables. Would our current motors work? If you have a rep in the NW Arkansas area that could take a look, that would be ideal. Once I received a quote, I would need to present it to the airport commission for their decision on proceeding. We work 7:30-4:00 M-F. Thank you Laura Meyers, Facilities Manager


Looking for a ballpark idea of what a strap upgrade would cost for our existing bifold door (uses 4 cables). It is approximately 40ft X 12ft. I hear your straps will also lift my door faster and will lock it in tighter to my building.

Looking to upgrade our old cable door to a strap setup. Need to know what the cost would be and if it is something that we could do ourselves?? ID plate says it is a S12 model No. 9 serial 4934.

I already know strap doors are quieter and faster.

The Schweiss bifold lift strap system looks tremendously more efficient than my old cable system that just recently broke again. Could you provide me a price list for a lift strap conversion system for a door that is 40 ft. x 12 ft.


Some of my cables are starting to fray but I also already have 4 straps installed, so not sure if I need a strap conversion kit? I have 4 straps now [in addition to the cables]so would more be needed to eliminate the cables? Can I send you photos of the cable doors and let you decide what is best.


My dad was a crop duster and passed away in 2003. My mom still owns the airport, however, we sold all the planes. The cables on the door are wore out and we can't use it and me and my brother would like to have it fixed and replaced with Liftstraps so we would be able to use the door to retrieve some trucks and vehicles inside. I know the width of the door is 50ft but not exactly sure on the height.

The hangar I rent has a steel door. It is a bifold door that is operated by a winch pulling 5 cables. It is a bad set up. The witch is ceiling mounted. What would a bottom mount strap system cost? How easy would it be to convert? I’ve had the door fall once when a cable broke. Two more cables have broken causing a very dangerous situation for my plane, not to mention my life. How far out are you for a conversion?. The hangar owner is is too cheap to do it right, which is why I am asking for the quote. Ballpark cost. Thank you.

Purchased my home a year ago, has a pole barn with a bi-fold door manufactured by you about 30(?) years ago as the original owner had a small plane. It uses steel cables, one of which has broken strands. The safety of this door is very questionable. Can Schweiss do the cable to liftstrap transition, or would you have a technician or easy to follow instructions so I can do it myself.


I have a 12 or 13 year old door, and the Latching cable on it has broken. I an interested in getting it fixed.

Good afternoon Ma'am/Sir, I would like to request some more information about your bifold door strap conversion. Currently, the building I am looking to convert the cable system for has 58 bi-folding wilson doors. There are also manual locks used to create a seal preventing outside air from entering the building when the doors are closed. My question is, will converting to straps maintain the seal so the manual locks may be removed? What if I want an automatic latching system from Schweiss? I have photos to further show what I am asking. Please email me back at the email provided if possible. V/R Richard Wilkens


Hi. I asked this question abt 2 yrs ago, and u sent me an estimate. Now I ask again: how much to change out cables for fabric lifting lines (straps) in my airplane hangar at KRPD, Rice Lake, WI? Door is Schweiss, Serial No. 39907. And can u do it this fall or can I do the install? And for how much? Plz note the door has been insulated with the rest of the hangar(so it is heavier than when installed). Might the motor, which runs ok, need to be replaced? I do not know. Plz reply soon as u have the first opportunity. I am very grateful. Gary Stelzer

I have a schweiss bifold with straps that works great, except the auto latch system has cables. My cable broke today so I am unable to latch the door.

Folks, I am in the process of planning to build a new hangar. I currently own a hangar with an older cable version of your door. I would like to obtain some very general price quotes for the bifold door with straps. My hangar will be approximately 50 feet wide and 60 feet deep with 12 or 14 foot sidewalls. I would like the door to be as wide as feasible for the width of the hangar but I don't want to sacrifice structural integrity. Can you offer some quick advice and some general pricing to include remote opener, battery backup, auto latches and windows so that I can better plan. Regards. Mike

We have a hanger door that we need to have worked on and with cables replaced with lift straps. Do you have any installation companies located in our area?


I have an older Schweiss hangar door and you guys have quoted me about two years ago on converting to straps. Now that I have seen how a fellow pilot converted his hangar door to straps I'm convinced that is the only way to go to get away from the hassle of a cable bifold door. Hope you can find me in your system. It’s a 46’x19’ I believe. I can send pics again if you need. Thanks


this is a follow-up on mine to you. I am assuming your records will tell you EXACTLY what I need. This will not be a "bidding war" - so you needed worry about bids from your competition. Your door has served me some 20 years now. Yes, I have had miner problems with your cable door. But the feature that makes me want to do business with you folks is - whenever I have had problems with your door, your folks are quick to help. That kind of support is priceless. Again, my primary interest is converting your existing door to straps.


Can you tell me the price of your strap conversion kits? I have one of your doors. It is a bi-fold door, single motor with a double chain and has five cables.I understand the conversion comes with a new motor (s).


We have a 20'w x 22't bifold door built by another company with 3 cables on it. What would the strap conversion cost, and could I get four straps to replace the cables?


We have your door on our hangar that hasn't been serviced since installed in 2002. It's working ok, but the steel cables are making a lot of noise going up/down and I'm thinking a preventative service call or conversion to lift straps might be in order. Do you have a company in Portland/Salem Oregon area that you recommend? Thanks


I have a nasty operating 42 ft. bifold from Erect-A-Tube. It's relatively old ~20 years. An auto unlock, bottom drive cable system. Dual capstans with ~70 ft. of aircraft cable per capstan. Cable is routed up and over, back down, back up, over and down to the auto locks. How much to convert to strap drive?


We have 3 hangars of varying size, all very old still perfectly working bifold doors with cables. We would like to see what our options are to upgrade to the faster opening and safer strap style door/possible self locking door.


I have a customer that would like me to quote a strap conversion that i believe they have already requested from you. This is a 100' x 30' (approx) hangar door with a bottom mounted drive system already. They have one motorhead with a worn keyway that will need to be replaced. Your strap conversion is an option no other company offers. Thank you!


I have a 38' bi-fold Schweiss door. I would like to inquire about the cost of the strap conversion kit. I understand this is something I could install myself with the Schweiss easy install directions you provide. Love my door especially in the winter because the bifold handles heavy snow loads very well.


I just purchased a hangar with a bifold door with cable lift system. I’d like to find out the options to convert to a revolutionary designed strap lift and what that cost would be vs a door replacement. My current door works fine, but I'd like to have straps to make my bifold lift faster and quieter.


I have Schweiss door serial number 12596-8. I recently acquired the airplane hangar with this door. I have a few asks. 1.

The cable is making a snapping/banging sound with every revolution. 3. I'd like to know what you recommend as the best bottom door seal to keep out dust, dirt, and critters. 4. I'm interested in the cost to convert to Strap Lift. I understand this will make my door lift faster and quieter.

I was looking at the strap conversion kits. How much would that cost and is that something I could install myself on our existing door? The bifold door by another manufacturer is roughly 16' wide x 16' tall and has 2 cables lifting it. The lifting mechanism is on the bottom of the door. I understand Schweiss can retrofit others doors with lift straps


I just had about a third of my pole shed collapsed from snow load. My Schwiess Bi Fold door survived but the two Manual latches that secures the door when shut did not.

We are looking for a parts list for your doors as we have a couple of clients that would like their doors converted to a bifold liftstrap system to replace nasty cables. Can you provide us with a list? do we need to supply serial number, model number?


I have a question about my bi-fold cable doors from another manufacturer that I bought in October 1999.  The door still works fairly well but I am worried about the unsafe cables and would like to replace them with Schweiss lift straps  Also, the hinges do not have zerk fittings and the crowded installation interferes with applying lubricant anywhere along the length of the hinge pin. I do not like it for the hinges to be working dry. I wonder if you have any recommendations for what I could do to enable lubrication, without having to hire a crew and equipment to dismantle the door? It is likely that I am not your only customer with this problem. Have you already worked out a solution? What do you think of the idea of replacing the existing hinge pins with new ones that have a zerk fitting located on one end? Those pins would be axially-drilled and that central hole would communicate with radial-drilled holes that would carry grease out to each of the three hinge segments. Would it be practical to use the new pins to drive out the old pins without have to dismantle the whole door? Thanks Jerry Jackson


I was interested in a quote for converting our bifold door from cables to straps. It is a (clear open) 70x20, I was surprised how much faster the strap doors open. Thanks

Hey Mike I built an unusual house about 10 years ago and it seems like it might be time for some remodel and update with new bifold garage and patio doors. The construction is metal building framed in with wood and exterior wrapped with Hardy Panel. Might be a real good application for a couple of your Bifold doors. I'm certainly into the use of strap vs cable. I converted some of my vent operators at the nursery to strap last year


I have a 12 year old 42 ft. bifold door. My question is about strap replacement. The cables look to be in tough shape, fraying and over wrapping. Just curious at what time frame should I consider for liftstrap replacement. I have 4 cables on a 14 foot tall door. ALSO, I have the cable system for the auto latch. Is there a conversion to your newer auto latch strap run system? Thanks John.

Hello, We moved a 96' x 56' Morton building to our farm from another farmstead. We are looking at different options for a bifold strap door on it. It has only three sides enclosed with one end open. We also have a 20' x 40' Diamond door in our heated shop. It has a seal across the top that is leaking water in whenever it rains.

Looking to convert 2 bifold cable doors to straps and see if your company does a yearly maintenance plan.


I have a Bi folding door with cables. It is located at Lake Hood and is a 16'x 55' door. I would like to convert it to straps and would like to know the details and cost of a conversion kit. also do you use a local firm here in Anchorage for these types of conversions?


Main lift straps (4 of them) on Bifold Door are good. However, the power Stranded Cable Drive (1 only) is fraying. Confirm the Strap Conversion Kits are designed to replace the Stranded Cable Drive and not the main lift straps. If that is the case, I plan to replace the Stranded Cable Drive with the Strap Conversion. If that is not the case I will probably need to replace the Stranded Cable Drive with a new Stranded Cable.

I have a 70 ft bifold door - how much to retro fit to schweiss' lift straps?? Please email


I have a cabled bifold door. Your material says you can convert doors that aren't yours, correct? if so please send me an estimate.


I have a 40' x 15' miracle truss cabled bifold door, looking to see what the cost would be to convert to straps.


How much to convert my 10' by 20' Schweiss cable door with straps?


I purchased a hangar/home that has bi-fold doors (probably vintage 1994?). It doesn't have straps, it's got cables. I'm unsure of the size but the hangar is 60'x50' and the door is probably 50' wide. I am looking for info on maintenance procedures. The door is a bit noisy when it lifts. I wan't to repair it, but I think upgrading it to the lift straps will be a better choice.


Please email quote for changing out cables for straps: 42'X16' clear opening. Four cables and my drums will probably accommodate your straps or I can cut/weld to fit. My electric motor with duel chain drives and limit switches are OK as is. Thanks Jimmy


We have Bifold Cable Doors from another manufacturer. Range from 50 to 110 feet wide and 24 to 35 feet high. We would like to get an estimate for retro fitting from cables to straps.

How much to retrofit straps on my Schweiss bifold door?


Hi: I have an overhead door. The kind that use aircraft cables to hoist up the door. I've been having trouble with the door lately. When they start opening up they sometimes stop before the set mark. I have to push the up button again and maybe twice. When closing the door the same thing happens again. I have to push the down button a number of times to fully close the door. I'm afraid to open the door now because, I may not be able to close it all the way. Rather than fix the cables, I would rather convert them to straps. please send me a quote for a conversion.


Hello, I am closing on my hangar in about a week and have already broken a lift cable! I bet you can guess were I'm going please help me with a strap conversation.


We have a large bi-folding door at a private residence in Miami Beach that still uses straps. The door no longer closes all the way, there is about an inch and a half gap still once the motors stop. Please advise, if the cost is in our budget, we may convert to lift straps. Thank you.

I have a 80's to 90's R & M steel building with non-Schweiss cable bifold doors. I am interested in converting it to a bifold door with straps and sky light panels or hole in the top section. My current door is 60ft wide and about 13ft high. I would like a quote including labor if you offer that or the contact for an Oregon crew to do the install. The bifold doors are serviceable but not sealed enough for the coastal weather. So as not to waste your time how 'bout a ball park quote to start with, so I can decide the feasibility of this project first. Thanks, Patrick, Please call after 8 AM PST since I am on the west coast.


We are needing to replace the lift and tracks and possibly rollers on our bi-fold tool shed door. It is 30'x16' steel frame door with a wood frame, post and beam building.

Email may be the best possible communication. Thanks,  Terry


I have a bi-fold door with cables for lifting, and it uses a cable system for the latching mechanism. It goes out of alignment and causes problems all the time, and the door does not always close correctly or for that matter, at all. I have seen your lift strap system online is there an upgrade path for the cable system?


I have a hangar with one of your doors with cables. The hangar door has access doors on both sides and I guess it is 50' wide. Two questions, A: if I wanted to convert to your strap system, could you give me a ballpark range on that cost? I don't need precision. B: the seal on the bottom of the door is a little rough. What would a cost estimate be for that. Is it an easy job? Hangar is in West Chester, PA. 19380.


Looking for a price quote for a 40' x 12' bi-fold door with straps delivered to Soldotna or Kenai, Alaska. Also, if I decide to use my existing door the price for the straps, etc., to convert mine from cable to your strap system. Thank you.


Hello, I have a cable lift bifold door, it's time to re-cable OR convert to a strap lift door. What information do you need from me about my door to do the conversion? About how much does that cost? Do you have instructions that I could preview? The door was originally purchased by Eustice H. of Centerville, WA in 1993 or so. Thanks, Aaron


Hi, I have a bifold door made by a company that is out of business on my aircraft hangar, which is 50ft across, each section probably about 10ft or so. On the inside, above the door, there is an opening that runs the length of the door. This opening has been covered with some type of 'insulation' that looks like it just hangs above the door from the frame. From the ground, it almost looks like it could've been made from felt. It's mostly disintegrated now, so there is basically this big gap - not good when I'm trying to heat the hangar. Do you know what I'm actually referring to? If so, can you fix this? I have photos and can send. I'm at a loss, so any help is really appreciated! FYI... my hangar door is about 14 years old, using cables. Is it worth while to convert to lift straps? Thanks again, Michael


What items are included in the lift strap conversion kits? Could you please provide a quote for a kit suitable for a 20' x 10'8" door Thank you! Kirsten

I am a tenant in a small airplane hangar with a Schweiss (vintage 2003) bifold cable door (Last maintenance was in 2013 with new cables, overhead pulleys and thimbles). I see several frayed cables with 1-3 strands broken and one of the safety cable guide springs seems stretched out. I am hoping to order parts from you (4 x 7/32" cables with stops (40 ft length each), new thimbles x 4 and 2 replacement guide springs. I think the overhead 3" pulleys are likely fine at 3 years unless you think that they are getting along in years. My other maintenance questions are: 1. What is the clear opening height of this unit? (If you can tell me with the model info?) 2. lubricant recommendations for zirk fitting parts and non Zirk hinges etc. 3. Does this unit have a "gear box" which requires 75/w 90 synthetic oil? I also see that you have a new strap system that looks very efficient, please quote me a price on this, if it's within my budget, I may just go ahead and convert the door to straps entirely.  Once you've digested all these questions can you please call me at 970 296-0967 in Grand Junction Colorado. thanks


I have one of your cable bi-fold doors. The three (3) springs that hold up the latching arm broke. I need the procedure to change them. It looks like I need to remove the cable, then remove the bolt that the arm swivels on to get at the springs. I'm sure that I can replace these, with some direction. Also include a price quote on upgrading to lift straps, I would like to do it if the price agrees with me. Most of the doors at our air park are your doors. Those that aren't wish they were. I live at Price Airport in Linden, Michigan. Thank you, Mark

I am from Owensboro, KY, my father and I were called to our local airport, Owensboro Regional Airport. They have some cables on them that are severally frayed. The sticker on the door is from a company that is apparently no longer around. This is the first time working on hangar doors and even though it's not your door, I was wondering if you could help us out. The airport is interested in upgrading to your lift straps as well, please send a quote.


We have an 80' aluminum hangar door from another dealer and would like to know if it could be converted to your lift straps and how much it would cost.


I am interested in buying a replacement seal for my 43' Schweiss bi-fold door. The original seal is of thin flexible rubber, approx 1/16", and is approx 42', 6" long. 10" wide would appear to be adequate. It looks like a simple project to replace it myself, so I am asking for a quote on that product, sent via least expensive means to Florence, Oregon, 97439. My second request to regarding replacing the existing cables with lift straps. There are 4 cables, and the door is approx 15' tall. Do you have technicians near 97439 that would do the retrofit? If so, I would like to get an estimate on having that task done. Or, is that a project that an average handyman could take on? If so, does Schweiss offer instructions on how to do that retrofit? Lastly, the bottom hollow rubber seal leaves a gap of approx 1" on both sides of the door. It seems to taper uniformly toward the middle, so I suspect it is due to settling of the collums, but I have not verified this with a builders level. How much of a gap should I expect a new bottom rubber seal to fill? Thank you for your consideration of these issues. Bill


I have a used home built counterweighted bifold door that I would convert to your strap lift system. Looking for a qoute. Door is 41'6" wide, 13'7" tall, frame is 1 1/4" 14 gauge square tube. I estimate it weighs around 700 lbs so let's call it 1000 lbs. Jim


We have a schweiss door on our hangar. It has been installed for many years and has worked very well. We have the old steel cables design and I see you are now using straps. Can we modify our door to update it? Being that the door is in a dry climate for the most part and sees temperatures as low as -20 F to highs of 100 F throughout the year. Is there any part of the structure that we should be worried about? The cables have been replaced once.Thanks David

Looking for service/repair on a bifold hangar door at the Crystal Airport. It is not a Schweiss door but would be willing to listen to an upgrade sales pitch on the lift strap system you promote. My motor and gearbox have failed and I think it may be due to the binding of the cable on the spool. Please help, Perry


We have an older Schweiss bi-fold door put in in the 90s. Wondering if you could just update it with the new lift-strap system. The old door has the chain and cable still. Thanks, Stewart


We have cabled bi-fold door from another company, and have found a frayed cable. We would like to upgrade it to one of your lift-straps systems if we can.


Hello, I see on your website that you now use lift straps with your bi-fold doors which look very nice and I am very interested in a quote to convert our steel cable bi-fold hangar door to your new lift strap conversion.


The Schweiss bi-fold door on my hangar is about 20 years old, operates with conventional cables using 120 volts, with hand-operated latches. Can this door be converted to the new 'strap' operation? With 120 volts? What will be the cost for conversion? Clear door opening is 38' by 9'6". And do you provide a kit?


We purchased 7 non-schweiss doors about 12 to 15 years ago and have the old cable automatic door latch system installed. I upgraded the main large hangar door with the newer heavy spring kit, but it is on an air life hanger door that gets very heavy use. the latch arms wear badly and the pins have to be welded up every few years or they wear through. Cable replacement is every year an the chain link in the cable drum has worn almost through the link. I keep cable lube on the drum and cable to help, but nothing prevents the fraying and wear on the cables. I have seen your new cable free latch system and wondered if I can retrofit my door with that easier than the strap cable combination of later design than what I have now. So far I have been able to keep the door working, but the door is out of service and the air life plane can not use the hangar if the cable breaks which it did again this week. I have to be on call 24/7 to fix this problem and if they can not get me they have to go out of service and can not fly. Thank you, Garret

I own a hangar at Akron, OH airport with a 42' bifold door, overhead cable style. The cables are starting to get wonky, and I thought I would investigate converting to Schweiss bifold lift strap with your new latch strap design. Not entirely sure who made the original door. Is there anything more to specifying your conversion kit, beyond "42' bifold hangar door?" What do you need to know so I can order the correct kit? How much does the lift strap conversion kit cost? I would probably install it myself. One of your testimonials mentioned that you give an EAA discount. Is that still valid? 


Hi. We have a bifold hangar door in VA from Schweiss. I am interested in hearing what it would cost to change out the cables for the lift straps. I noticed there was a kit for it, any chance I could get a quote on the cost for that? Also, I want two door remotes for my other hydraulic shop door. Thanks, Adam

My cable-lift door in WA is now 15 years old. The cable guides on the main shaft are wearing on one side as a natural consequence of running up and down the cable. I'm ready to do a liftstrap conversion and I would like a remote opener for the door.


I purchased a TN hanger with your cable door. (55x16). It is now creaking very loudly. Also my autolatch does not pull in the left hand side of the door tight to the frame (looking from the inside). Could you give me a price on a liftstrap conversion and include a remote opener?

I am purchasing a home with three barns located on the KY property. The large machinery shed has 2 cable bi fold doors, that I am not sure who the manufacture is yet. I am trying to determine the cost to replace these doors in case something would happen (insurance coverage). I want to make sure that my insurance coverage takes into account these doors. The first cable bi-fold door is 30 feet wide and opens up to 14 feet high. The second cable bi-fold door is 40 feet wide and opens up to 16' high. Looking at the Schweiss Door website I see you have a liftstrap conversion kit. If I send you photos, can you tell me if the entire doors will have to be replaced. 


Can you please provide me with a quote to covert four Schweiss bi-fold doors from cables to straps with strap latch design? We have three (W31'x H20') doors in DC with four vertical cables and one (W51'x H20')door with six vertical cables. Thank you.


DSM is running into a few issues with the hangars at one of our FBO's, and was wondering if you would be interested in reviewing. Looking at options to see if we cannot retrofit existing cable system on another manufacturers doors with lift and latch straps, or if new bi fold doors are required. Looking at 3 hangars with issues: 1. Building No 8, qty (3) doors a. (2) @ 20' H x 60' W b. (1) @ 25' H x 70' W c. Interior cables 2. Building No 9,  qty (1) door a. 21' H x 80' W b. Both interior & exterior cables 3. Building No 10, qty (2) doors a. 22' H x 79' W b. Both interior & exterior cables All have bi fold doors being raised by cables. Height was estimated by measuring to top of bottom door panel. Doors are starting to bind, snapping cables quite frequently. Would love to determine if you can restore the doors or if the doors are shot and need to be replaced or if bifold door liftstrap conversion kits will solve the problems. Have photos of MO project if you would like to review.

My 1998 cable maintenance facility door chatters when going up or down and I'd like to retrofit it with your Schweiss lift straps. This is not a Schweiss door, so will your door liftstrap kit work for me? 


I purchased a 40' Schweiss bifold door from you in 1995. My 4 pulleys have worn substantially and I'd like to retrofit door with your liftstrap door conversion kit.

I purchased one of your bi-fold doors about 9 years ago on my garage. I live on the side of the mountain without a lot of room to turn around so I didn't want traditional garage doors.  How much does the conversion to the new lift strap bifold door run? Mine is the old CABLE lift door, and I'd like a low maintenance liftstrap door. This garage door  gets opened and closed often. Do you sell extra remotes separately for the door? I noticed on your website that the remote is different now -- Will you new remote door opener give me better range and will straps make it a faster opening door?
