Schweiss Doors is introducing an all-strap bifold door! Straps do the lifting and now straps do the latching too! It doesn't get any better than an all-strap door. The simplicity of the new latch strap is truly amazing! Schweiss did away with all the outdated cable-lifts, chains, sprockets and pulleys; strap lift doors now have 90 percent less moving parts.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.
