No Noise, Creeps or Crunches with Schweiss Liftstrap Conversion Kit

Schweiss Doors revolutionized the bifold door with faster, safer, quieter, longer lasting liftstraps and autolatches. No matter who made your door, if you currently have cables on your bifold doors, Schweiss Doors now has an easy to install liftstrap retrofit conversion kit available to upgrade your existing door. Schweiss designed and patented custom-made polyester lift straps provide a new and much safer alternative to steel cables. No more cables or pulleys to adjust.

Liftstraps offer more lifting ability and will vastly outlast cables. The strength-to-weight ratio on our 3-inch straps are rated at 29,000 lbs tensile strength, compared to a quarter inch cable which only gives you a 7200 lb rating. The lift straps wrap around the lift drum as the door opens, increasing the size of the drum. It’s ideal: the door opens slowly at first and quickly picks up speed. Schweiss liftstraps, never rust, never tangle or over wrap and are warranted for 10 years. They’re also available with auto latches and remotes.
