My existing old style sliders need to be replaced with something easier and more reliable like your Schweiss Bifold door - opening is 27ft wide X 14 ft 7 in height Can it be retro fitted with on of your doors? Pole barn is 1994 Cleary. THANKS 


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,

Retrofitting door into existing metal pole barn, replacing two standard sliding doors with a couple of vertical lift doors with straps.


I just purchased a hangar at X04 and unfortunately the old 60' Carolina bi-fold door is installed. Do you offer a retrofit of your opening system for this door? If so, any additional information would be greatly appreciated. If not, what would a replacement bi-fold door cost? Thanks in advance for your help. I need to get the exact specs of the door opening. 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. I probably need someone to look at the building and tell me what will work. but the idea behind having a temp wall there is perfect. These will go in as a replacement for a load bearing wall. 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. Our old hangers have sliding doors and it was brought to my attention that if we could put bi-fold doors on our old hangers more people would be interested in renting them. Is this something that you would be interested in. They would look a lot better with windows. in the quote can you please add a remote control to open automatically.


I have a 50' Wide by 12' high sliding door opening in my wood frame Aircraft Hangar and would like to replace it with either a Bifold or Hydraulic door. I need a walk through door framed and a 3 button dead man switch.


I have an older bifold door that uses 3/16" steel cable that mounts on each end and the center goes to a spooler. Would it be possible to replace my cable system with the strap system?


I'm considering the purchase of 60' wide and 50' deep and 16' high metal building. It's a metal frame with i beams and has an accordian type door. The door is on the 60' side and is 12-13' high. Right now I am looking for a very rough estimate of cost of a complete bifold door with strap system to replace the old door. I'm trying to determine if the hangar is worth the cost.


Hi We have a shop that is enclosed by custom made garage type doors. We are looking into upgrading to a lift strap bifold door and a new motor combination for them. If you could please send me any information (such as spec sheets, gear ratios, length of straps etc), it would be greatly appreciated.


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.




I would like to replace the cable lift system thats on the hanger now with a strap system. Is there someone in the Bakersfield Ca. area that can install one ?


I am looking to replace a door that was damaged by hudrricane winds. The building is a pole building (built in 2008 by the local lumberyard) used for machinery storage and is not insulated. I would prefer the straps over the cable system and have it wind rated.


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!!!


Good afternoon, We currently have multiple large overhead steel doors. They tend to cause us a fair amount of downtime, due to age, and probably size. We are interested in alternative hydraulic or bifold Schweiss style doors that either slide or open similar to hanger doors. Our current doors are roughly 16 ft wide x 27 ft tall. If you have any alternatives to this we would like to discuss. We have a total of 9 doors that we would like to replace one at a time as they fail.I will be out of the office until Wednesday, so please feel free to email with comments or contact via phone tomorrow.


Is there a way possible of making this door 2 ft higher in the center to fit a higher tail aircraft in? The customer in this building would like to gain 2 feet in the centre of the door to accommodate a higher tail aircraft he is getting.What would the cost be for a center pce that could be added to this bifold door.  We put this door in this summer please let me know if any questions 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. I am interested whether one of your hydraulic doors would be able to be fitted, the width of the door required would be approx 13 metres. I am looking at the moment at a budget price to see whether this option would be worth further consideration.

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

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.
