I'm an architect Looking for structural/electrical coordination info as well as details for a 100' wide by 28' tall bifold Liftstrap operated hangar door. It will be installed in pre-engineered steel hangar. This is for an FBO/Hangar project at the Eastern Iowa Airport in Cedar Rapids, IA. We would also like to clad the door in polycarbonate. Thanks in advance.


I have a 36'x12' opening in my steel framed hangar, I am after a bi-fold strap door that can operate on 12V or24V as we are off grid, I understand I will loose 2' off the vertical due to the bi-fold which is fine as the hangar houses Experimental aircraft, not that tall. Would also like to operate with a remote. Can you help? Geoff


Hi - I have 2 questions regarding a current project in design. 1. We are working through the design of an electrical vault with overhead doors but would prefer an electrical lifting bifold strap door - do any of your products have a 3HR fire rating? 2.

Hello, I am working on an aircraft hangar project with many box hangars using your electrical lifting power operated Bifold doors. My question is can the doors be operated on 208V? That is what we have available on site. My other question is how many amps and/or HP do the doors require. The max size of door is 58'W x 21'H. Thank you!


Is there a way to get a wire diagram for an older door system? It is an older lock system for a biofold door. The main controller was replaced and I need to wire in the door lock/latch. I can provide photos or other information as needed. The lock/latch has a reversing contactor controlled by a relay. It is a telemecanique contactor. Please reply by email. Thanks, Patrick Colwell


I am working on a model SCH-5, Serial number 152916-27, manufactured 6/5/2006. There is some wiring that has been disconnected by a previous owner. They did not leave any kind of documentation or wiring diagram for the bifold Liftstrap door controller. I have looked at your website but haven't been able to find anything. I was wondering if it is possible to get the wiring diagrams at least for this door? Any additional documentation would be a plus if available. A document link would even be great if available. Please advise. Thank you


I'm an electrical engineer and I have a project that has spec'd (3) 26' x 16' Bi-Fold Door with liftstrap and autolatches.

They haven't decided if they are going bottom drive or vertical top drive, so if you could send me those as well, I'd appreciate it. I looked on the website and couldn't find it so if its there, I apologize. Thanks!

We have door S24, No. 452-2, Serial7619. This has a separate motor to run the door locks. When the door closes, it starts engaging the motor for the door locks.

Is there a wiring diagram we can get for this door? Is there a local company/person who can work on this door? Now that winter is starting to set in, we need the door to close and lock.

We have a bi-fold door and over the past few months, I've come out and seen the door open a few inchs. I'm guessing that someone here close by has a remote opener that is reacting to my door.

I'd prefer to change the code if possible. How can I do it?

We've been working with a company and their electrical lifting airport hanger bifold door for a while now that has existing cables and pulleys.
