Cables are the old way. Everyone knows cables have a tendency to fray over time. Frayed cables can break and doors can come crashing down on aircraft, machinery or even people. Cables require more servicing, are hard to work with and difficult to replace. Replacing cables with more cables is a timely and costly expense and can be a real safety issue if the cables are not kept in good condition.
Schweiss has figured out and designed a way to modify any bifold that's ever been manufactured. Retrofitting an existing cable door over to the Schweiss design "Lift Straps" on other brand bifold doors, no matter the make or model.
Schweiss has brought relief to customers with the old vintage cable bifold doors. Finally, the customers with cables can be at ease. They're able to do away with the antiquated cable lift design and retrofit any style or brand bifold door over to the latest and greatest Schweiss "Lift Straps."
The strap advantage is huge. Straps are longer lasting, never rust, never tangle, are flexible, open a door faster and are 100 percent quieter than steel-on-steel cables. With lift straps, door owners get a "soft start" and "soft stop", adding to the life of the bifold door. Schweiss stands behind the "New Lift Straps" by carrying a 10-year warranty and straps outlast cables well over three times.
"It's not your bifold door. Can I buy just the 'Lift Straps' and convert my door over to the straps?"
"Can you convert my cable door over to straps?"
"My door frame is good but I'm tired of changing out cables every couple of months!"
"Will your straps work on my door, its another Brand?"
"I was at the neighbor's hangar and saw how smooth and fast a Schweiss Door operates. Can you help me?"
"My door is not that old but I hate my outdated cables. Can you convert my door to straps and autolatches?"
"I see your strap doors are much faster than my outdated cable door. What's it gonna cost me?"
"I was trying to save money by going with cables. Boy, what a mistake!"
"Why would anyone even consider outdated, slow cable doors today. I wish straps were available when I purchased mine!"
"I still like bifold doors. Now with the straps and
auto-latches they're even better!"
"Nobody will sell me another cable door!"
"The Strap conversion made my door better than new!"
"What a nice Improvement to an older door!"
"Straps and auto latches, what a great improvement!"
"You guys are good, thanks for the neat invention!"
"Should have done the strap conversion years ago!"
"If anyone asks. send'em my way and I'll be your salesman. I love my door now!"
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.
P.S. Has anyone ever converted a strap door
back to cables . . . I don't think so!
Cabless require more maintenance meaning more down time
Loose cables cause problems
Cables wear out faster and fray easily over time
Schweiss Lifts straps have proved to be by a far superior method of lifting any bifold door. Lift straps wrap on top of themselves by design. No worry with overlapping issues or with cables rubbing against each other. Furthermore, everyone knows that cables are not even close to being as quiet as liftstraps. Can you imagine the noise that 10 or even 50 cables must make?
