Schweiss Doors has done away with all the cables, chains, sprockets and pulleys with its new strap latch assembly, and its bifold doors now have 90% fewer moving parts. As a new design from Schweiss Doors, straps do the lifting and now straps do the latching. Unlike other bifold door latch mechanisms, the new Schweiss design will reportedly hold the door against the building in all positions, securing the door when open/partially open, and will firmly lock the door when closed. It offers added protection from wind gusts while the door is in any position during operation. This innovative strap latch requires no extra motor, and it pulls the doorframe securely against your building making for a tight seal with each use.聽
