What People Are Asking



We have a bifold cable drive door and are wondering the manual opening process if a failure occurs because we now have a med vac helicopter in the hanger all input is valued


I bought an aircraft hangar with an electric schweiss bifold door. In case of a power outage, is there a manual way to open/close the door? Thanks


Hi I need a one-piece hydraulic hangar door 39 feet by 10 feet 6 in. Our building is prone to power loss so we will definitely need a manual door backup system in case of emergencies. Thank you


Need a lift-strap door for my barn, 14' high x 15' wide. No electricity yet; can one have a manual door system which can be switched to electric later? Is there a price range for this size, please?


I would like a formal quote for the emergency backup hand crank for bi-fold door, let me know payment options also. Thank you, Gary


Hi, Just contacting you to see what is available for our Hangar door in Kingston Jamaica. On a regular bases the power in Jamaica is "Dirty, loss of phase " so we rely on a back up generator to open the door from time to time. Last month our New generator had a Voltage regulator failure and we had no way to open the Hangar. Is there a Battery back up unit, or chain fall system available? regards Robert, Hangar Manager


I am looking for a hydraulic powered hangar-style garage door to replace an existing standard "up-and-over" 2-car garage door. I also need an electrical  backup system in case of power outage and power/remote garage door opener that is not installed overhead.


I have no electric power. Can i use a solar panel and 12 volt battery to power a hydraulic hangar door? If not, I may be interested in a manual backup system. This would be for an aviat husky in AK. Thx. Richard


We will be needing four insulated overhead bifold recycling center doors each 25' wide by 20' high. We want Schweiss lift strap doors with a couple of remote door openers for each door to give to our drivers. They should be equipped with manual door backup systems.


Looking to raise a 60x80 shed and need pole barn machine shed doors on each end. Walls are 14', thinking of going up 3' maybe a 40' wide? Submit price with door liftstraps and walk door? Manual latch door system is fine.


I own an hangar 12 x 15 meters. I have a manual system of the door, and want to change for this system. I live in Mexico. Can you send me information about prices, plans, construccion etc. on your bifold and hydraulic Schweiss Red Power doors. The hangar I have is block construction with wood roof and shingles. Wilt 


Hello, I am in the market for a new bifold door for my shop. The opening is 16' x 12'. and I have 2' of additional wedge room. So the door size I'm looking for is 16 x 14. It's a sturdy 2x6 wood building, built in the 80's. Size of the building is bout 30' x 40'. The building is heated, so the door would need to be insulated. I'm looking for a price, and any additional things we would need? Do you think we'd need a free standing header? Possibly a couple small windows for light? Also, can a person get a manual lift instead of a power one? Thanks. Hope to hear from you soon, and hope we can do business.


I have your bi-fold door and it is installed. The electricity is out (for quite a while) and I am out of town from the building but I have a friend who lives nearby. Is there a way to manually shut the door? Thx, 


Concerned about operation of bi fold door in case of power or equipment failure--how would one open/close? What kind of back up system is available, or option to operate? Thanks


1. I am looking for a single car bi-fold garage door. 2. Desire simple low tech manually operated door for installaiton in an existing block wall construciton garage. 3. Can you email me: a. Photos of standard bi-fold doors b. Dimensions of door and required opening c. Prices and or range of prices before shipping d. Distributors in the Norfolk, Virgina area Note, if you call, be aware that I am currently in Baghdad. It would be best to email and provide a time and POC for me to call you. Thanking you in advance.


Would you please email me with the cost of the manual door crank for our bifold doors?  I am referring to the emergency crank in case the power is out. Also, do you know how long it takes to crank down a 50' or 60' door by hand? Thx.


We Purchased a door from you I believe in the fall of 2006. Electric ( 2 motors) Strap door. Anyways we have had a couple of instances this past winter when the local power system has been down for extended periods of time. I do remember there being some sort of backup opening system as an option. My question therefore is: Is there an alternate backup system for our door. If so what is the cost and how does it work. Regards Hans


Hydraulic doors: Can these be setup to us manually? Don't have electricity. Or can a gas motor be attached to your Red Power pump. Can they be insulated? I need a door that I can seal for root cellar. to keep cold air out.
