New Schweiss ‘Strap Latch’ design eliminates cables and pulleys

Bifold Doors / Hydraulic Doors

Just when Schweiss Doors thought it had the best automatic latch on the market, the Schweiss design team did itself one better. This “new,” totally functional and simple strap latch system gives you an “all-strap” and “only-strap” bifold door. Schweiss Doors recognized that straps that used to do the lifting, could now be designed to also do the all-important latching; thus making it the only “all-strap” bifold door and giving you by far the best autolatch system on the market!

Schweiss Doors design team came out with patented liftstrap doors in 1998; a proven design for over 15 years. Now the new Strap Latch “total strap design” is the most recent major breakthrough in the bifold door industry, and it comes only from Schweiss Doors.

Some manufacturers still continue to try and sell cable lift bifold doors — cable doors that not only require frequent maintenance due to fraying, breaking and overwrapping, but which also open much slower, are hard to adjust, are not as safe as straps, and are noisier than liftstrap doors. In today’s world, you wouldn’t buy a car without air conditioning, so why would you buy a bifold door without liftstraps. Cable doors are now outdated!

The simplicity of the new latch strap is truly amazing!

Straps do the lifting and now straps do the latching! Schweiss did away with all the cables, chains, sprockets and pulleys; and it now has 90 percent less moving parts. This is a real game changer in the bifold door world! It doesn’t get any better than an all-strap door.

It will fit any size door and can be retrofitted to any door with no loss of headroom.

This is what every owner wants and needs. Unlike other latch mechanisms, the new design will securely hold the door against your building in all positions; securing the door when open, partially open and it will positively lock the door when closed. It will even secure the door from wind gusts when the door is open, closed, or in any position as the door is in a moving operation.

It uses the same highly acclaimed liftstraps that are capable of lifting 29,000 lbs. each. Motors can still be mounted as top drive or bottom drive.
People visiting Schweiss Doors at farm, air and architectural shows were in awe when they saw the new Schweiss Autolatch system in action.

Here’s are samples of what we are hearing from our customers:

“The thought process and mechanical aptitude to create the strap autolatch and lift strap system is quite ingenious. It’s hard to say just one thing I like about my Schweiss door. I like the engineering, the quality of the door, I like the operation; the way it lifts up and down nicely and seals well. I think you guys did an excellent job on my all-strap door.”

“Straps are the only way to fly – no noise, no creeps, no crunches. Cables wear out.”

“The straps were pretty easy to install. They are quieter, quicker and safer, and the safety shield system is really nice. I’m real happy with it.”

“The straps were pretty easy to install. They are quieter, quicker and safer, and the safety shield system is really nice. I’m real happy with it.”

“I’m very happy with the liftstraps and I wouldn’t be without the auto latches.”

Schweiss says:

“The strap latch is so simple . . . I can’t believe we hadn’t thought of this until now. The straps do all the latching!”

In conclusion, the new latch strap system is what every door owner wants and needs. It is safer, simpler, easy to install and comparable in price to the previous autolatch system.

  • Straps secure the door in the open position
  • Straps secure the door in the closed position
  • Straps secure the door in all positions
  • Straps secure the door from gusts of winds that may occur as the door is traveling
  • No cables, no pulleys, no chains and no sprockets to deal with.
