Schweiss's excellent success with the New Lift Straps has revolutionized the door industry. It's a no-brainer. Why bother with cables? It becomes obvious when you understand why the new patented Lift Straps are the smarter way to raise and lower your bifold door. Smoother, safer, faster and quieter. Like a customer once said, "My strap bifold door is the envy of my fly-in community. I'm happy I bought the Schweiss Door!"
For years, bifold doors have been lifted and lowered by the conventional means of steel cables. Schweiss Doors have been using the popular, long-lasting lift straps for over 20 years. Now 99 percent of our customers are demanding polyester lift straps for this function. Why? Because lift straps offer more lifting ability, won't fray or overwrap! The strength-to-weight ratio on straps is extremely high. The 3-inch straps are rated at 29,000 lbs, where 1/4" cables are rated at only 7,200 lbs. In addition, the safety factor on straps has well over the standard 5:1 ratio.
