I made a Bifold door for my garage but i need the system to open automatically. I think in hydraulic system but after see bi fold strap think is better for me. I compensate the weight of the door with square weight pieces. The door is 7.4 mts width and 3.40 mts height the weigh of the door is aprox. 600lbs. Please let me know what is best for me and the way I can order it. Thanks


I have a smaller wood-framed hangar door built some 20 years ago on Timber Basin Airpark, Sagle, ID. The existing doors are extremely simple, free-hanging doors mad up of 4 panels that are pulled together. I wish to explore to retrofit the existing hangar door with a schweiss bi-fold door mounted above the header. The existing size is 38' wide by 30' deep and 16' to the top of the header.


Do you have a solution for wear in the cable wrap guards on older cable lift bi fold doors? I have some pictures available. The cable wears its way through the pipe and begins to snag the cable. This leads to cable breakages. Or do I just convert to the strap bifold door system?


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...

We have a bi-fold door installed at our warehouse I don't think it's your door but it has a malfunctioning motor. I was trying to get in contact with someone who can come out and troubleshoot/quote for repairs. Any information is greatly appreciated. Thank you.


Good Morning We have 5 Bifold doors at our faculty, I need a quote on a new window for our door. I was also looking at your website and am interested in the auto strap latching on the door. We currently have the manual steel handles to close our doors. Would this be an option to retro fit our doors with? Then could we use automatic openers on our doors?


Good afternoon, my name is Scott and I'm with Precise Door Co in Traverse City. We are doing some work on the Manistee airport on their cable bifold door. We are looking to add Wind Lock Pin with Strap to a cable bifold door, also need to order 10- cable tensioner springs.I haven't been successful trying to purchase these items so I was hoping you could us find an avenue to do so. Thank you in advanced for looking into this for us.


The hangar project includes the removal and replacement of two insulated bi-fold hangar doors (~ 60’x 21’ clear opening) and the associated electrical work for the door operators. I sent an invite thru ISQFT where you can access the plans and specs.


I have a Port-A-Port Executive III hangar at RDU airport. It has two side doors that fold and open sideways, plus a giant center door that lifts without folding, using cables, springs and an electric-motor-driven, Overhead Door brand, chain opener. When lifted, the door is 90% inside the hangar, over the area where the plane fuselage is. The door is about 18' wide and probably 18' high also (roughly). I want to know if I could use one of your doors to replace the center door that I have now. The opening mechanism of my door now is not very robust. The newer hangars at RDU use your folding doors; although their design is very different. They have one wide door, rather than small side doors plus a large center door like mine. Please let me know if this would work and also what the likely cost would be. Have you done this ever before? Thanks.


Can your company RETRO -Fit bi-fold doors to current sliding T-Hangar doors ?? not sure which type of your door would be best for our application --need some direction on this does you company do the installation of the Retro-fit T-Hangar doors


My two buildings (Salix, IA 51054) are Butler 40'W x 120'L x 13'6"H (sidewall) built in the 1950's. Current openings are 16'W x 14'H, with vertical I-beams on each side. These buildings were originally built to store grain, so are constructed with extra steel for strength. These are regular, straight wall buildings, I think the roofs are 3:12, maybe 4:12 pitch. One or both buildings will be having new insulated sandwich panel siding installed in place of the current uninsulated original galvanized siding. Maybe this same insulated sandwich panel siding can be used on the doors? It'll likely be Hardsteel Brand, possibly Butler. Door openings currently have no header, the original doors were sliding. Contractors Need estimates of price and timeline for delivery, and hopefully, installation of four, 16'W x 14'H insulated bifold doors, installed. Please contact me with any questions. Thanks. Tim

Their sizes range from 8ft x 4ft up to 12 ft x 7 ft. I understand that some of those doors will not be available in a smaller size. I'd like an opportunity to send someone some reference material for our project and speak about options and recommended solutions.


I've got a door that I would like to get a price from you on retro-fitting to the strap system. What all do you need from me?

Pete Olsen and I purchased a door from you recently. I was looking over your site today and noticed a new auto latch system.

What would these cost for our door ?


Buying an aircraft hanger. Need to modify the cable lift door opening to a liftstrap door that has a 48 x 15. What is the cost of a bi-fold door with these dimensions? 


Have sales rep call me please. I have a bifold door. The cables must have doubled over somehow and broke the closing arm springs. I would like to visit about what is needed to retrofit to a Schweiss liftstrap door system.


In 2015 White River Helicopters' new hangar was built with a Schweiss bi-fold door. I haven't found details on a model or serial number on the door or motors. It's been working great, but this summer we're noticing that the cables are fraying and would like to get a Schweiss retrofit to liftstraps.  I've been looking around the office/hangar and haven't found copies of the installation/maintenance manuals. Would it be possible to get copies by email? We asked an out-of-town overhead door installer to look at it several weeks ago, but they were not familiar with the door and made the situation worse. I've since had our aircraft mechanic readjust the cables  again so it mostly closes, but there's still the same size of gap we started with. He's of the theory that the cables should be converted to liftstraps also!


we are looking for different options for one of our current door openings to the shop. Current roll-up door is 22'W x 16"H. Looking for a ballpark quote for bi-fold door. On our interior is where problems occur due to limited space from top of door to roof beams. Appreciate if you can provide ballpark pricing.

We are investigating the possibility of retrofitting a pair of bi-fold, cable lift doors (residential application) with hydraulic cylinders. This will require the removal from the existing doors, the strap drive, gear box , drive shafts etc. The long-stroke ( 9 ft?) hydraulic cylinders will be placed vertically in parallel with the existing building door frame vertical members. What would be the approximate cost of purchasing both the hydraulic power unit, 20 ft hoses and two double acting, long stroke (9-10 ft) cylinders from Schweiss ? This is a budgetary cost request only.


I don't know what company door it is. I have a 81'x200' Shop with two 40 foot hydraulic doors. One of my doors if it is fully extended open and whenever you go to close it, it pulses whichs puts a lot of strain on the door frame. I would like to replace the system if I can, please advise.

I need an estimate for a Schweiss door to retrofit a 7' tall by 8' wide opening. We are restoring and adding on to an old gas station. The opening is low-overhead, so a traditional roll-up door won't work. I would like the door to be similar in style to the other garage doors on the building - traditional gas station style, aluminum framed, glass panels except for the bottom row which is solid. I was leaning towards a bi-fold door, but a hydraulic swing out door would work in this space too. I can pick up and install the door.

The building is wood construction the rafters are 2x6 tops and 2x4 bottoms with 2x4 webbing the building is quit old. It has 4x4 door posts I currently have an overhead door that is worn out. After looking at the doors you offer I think retrofitting the old doors with one of your bi-fold garage doors would work with the out side frame not sure the door opening is 11ft wide and 12ft 6in tall. The 4x4 door posts are in cement at bottom and fastened to the rafters on top. I am looking to have the door to rise level or above the bottom of the rafters I need the entire 12ft6in so I can put an old camper in side so I can work on it.


I am interested in getting a quote on retrofitting my existing cable bifold door to lift straps. The door has 5 lift cables.


I have a shed that currently has the sliding doors that come together when closed. I would like to retrofit in a hydraulic shed door in place of those sliders. My big issue is, the opening of the door isn't 14 foot tall and that is also the wall height as well. I cannot afford to lose any of that clearance and I was wondering if your doors would accommodate this? Also what would be a rough price on your doors. I would have to measure again, but I think the door opening is 14 foot high by 22 or 24 foot wide. Thanks

I just bought a 50 year-old house in Bakersfield, CA with an airplane hangar attached.

The header is exactly 10 ft. above the concrete floor. The opening from side to side is 48 ft. with some concrete door supports on the inside  corners. We would like to keep all of the 10 ft. hangar door clearing. A local contractor can modify the front of hangar and install the new Schweiss folding hangar door. We intend to insulate the hangar door, and install heat. So, we need a Schweiss insulated folding door.

I live in a senior community with a home owner's association. The four section insulated garage door I have now extends over a third of the way into the garage when it is in the open position. I would like to put a car lift in the garage and thus need an alternative garage door that does not extend into the garage when open. Can my existing 4 section insulated door be converted into a bifold door (the HOA would not allow me to have a garage door that looks different from the one currently installed) and if so, at what cost to have a completely operational door. Also, if this were done, how much heigth would I loose in the door opening when the door is open? One door is 8' tall by 16' wide and the other is 8' tall by 8' wide.  Martha


Do you sell and install your doors? Also do you do any necessary building modifications so that the door can be installed for maximum use? The existing building has an opening that needs modifications made to it so a larger door can be installed so that our township road grader can easily be moved in and out of the building. The opening size is an estimate because we need a salesperson to come out and tell us exactly what we need. Thank you,

I think the opening is 20 ft. high.


I spoke to a couple of reps at the Louisville show. I need a few schweiss bifold doors to go in an old school.

The building is a brick/block wall with 2/12 rafters.


I have a Kansas customer looking to add lift straps to a bi-fold door, looking for any words of wisdom regarding such. Thanks


I am a board member at Airport and recently we just finished 6 new hangers with Schweiss Bi-fold doors.

I'm just trying to get and idea on cost. Need to enlarge the end on my building, maybe a project for this year. Have seen some bifold doors in the area, did a search of the web and found your web-site. Have looked at the information on the web. Based on the info I looked at, a 27 wide x 14 high bifold door with a 2' wedge will work with the existing columns.

This will replace 2 existing sliding doors with either bifold or hydraulic doors. The measurement that I send is the exact opening of the hole.


 I would like to use one of your hydraulic single panel, swing up doors in a building I constructed. It was originally designed for two rollup doors with a removable verticle post. After seeing your ad I'd like to switch over. The rough opening is approximately 8ft high and 25ft wide. It is a wood building and the opening consists multiple 2x6 jack studs and 2 - 3ft x 26ft flat roof trusses for a header. There is no roof or floor loading on this truss assembly, it only supports itselt and a small knee wall above it. I have an engineering drawing of the truss/header assembly. The concrete floor has not been installed yet as I'd like to install the door first. What specific information do you need from me so you can make the most accurate quote possible and guarrantee me a trouble-free installation. I would like to send pictures so please let me know where to send them. Thank you!!!

Here are some pics of the rear doors. You have a upper bifold door that basically pulls up tight to the upper structure of the house, due to a bridge crane that has to pass by door to exit rear of machine and two doors that swing out. Currently, upper door is raised and lowered by a winch/cable device and two other doors swing out by manually pushing and pulling on doors. If you think you can be of assistance please advice us in options available and pricing. We can also arrange you to look a tour application for questions and dimensions.These are pics of our Dragline, we have a 8100 and 8200 dragline that will also need opening devices installed. They both have two sets of doors that swing in instead of out. Here is a pic of doors like installed on 8100 and 8250 Draglines.


We currently lease a Hangar, with the normal large Hangar Doors which are proving difficult to open and requiring continued maintenance.

Recently a Schweiss Door was installed at the Wausau Downtown Airport (Wisconsin). The owner is very pleased with the door and the lift strap system. The City of Wausau also owns a 100x100 aircraft hangar with a bifold hangar door mounted in a rough opening of 31'6 by 80' (28 ft clear height). The door was installed in 1997 and was manufactured by another hangar door company and has a archaic cable lift system. We would like to inquire whether this door could be retrofitted with the lift strap system as the cable system has caused some problems. Please contact m to discuss the possibilities for retrofitting the door. David

You installed bi fold doors at the Lancaster Airport in PA about 4 years ago. They went onto a row of box hangars. The hangars are 55 wide by 50 deep with I believe an 18' door. We currently rent one of these units and are curious if it can be retrofitted with the automatic open feature... Can you let me know if yes or no...if yes...the cost... Thanks, Chad O.

Good afternoon! I'm interested in the straps which you have that can be retrofitted to a cabled, bifold door. However, I'm not even sure the door on my hangar is one of yours. It looks very similar but I cannot find any markings or label. I could send you a picture. The t-hangars were built in 2003 and it is 42' long by approx. 12' high. I'd appreciate any information you could give me. Thank you very much! Steve

We are in budget prep and would like to include replacing a specific number of bi-fold door operators per year in our plan. We currently have original top mount electric operators running a v-belt drive with a mechanical brake that turns a cable drum for three cables. The hanger was probably built in the 70's and the operator has no markings to determine what make it is. The doors are 40' wide and I think 14' tall. We are looking for a price to convert to a new operator with minimal retrofiting. Have you ever provided new operators for older existing doors and or what would you suggest for upgrading. Kevin

We recently built a 60 X 96 building. The door on the south side of this building is less than we expected. We would like to consider replacing it with a bifold door. The door measures 16 X 30.
