Schweiss Doors bifold lift strap doors have a unique design, including patented heavy-duty lift straps rated at 29,000 pounds tensile strength that are evenly located throughout the entire doorframe to provide even lifting. The lift straps wrap around a spool to raise and lower, increasing the operating speed and ensuring a quiet-operating door. The doors do not require pulleys. Because the doors have two sections – a top and a bottom half – they hang out half the distance of other doors, which puts less stress on the building.
