Aircraft Grade Cables to Efficiently and Securely Open Your Door
Hi-Fold doors are delivered completely rigged with 7/32″ lift cables. A strict 5 to 1 safety factor determines the quantity of cable lift stations for each door. Our cables are secured to the top rail of the door. As the door rises, the cables wrap around large diameter drums on the full-width drive shaft. We design our cable lift system so the cables wrap right to left without ever wrapping over themselves. Cable guards cover the lift drums to protect people, clothing, and pets. Lift cable “poppers” automatically push the center hinge away from the building as the door rises.
We are so sure of our lift cable design, we offer a lifetime warranty on all of our lift cables.
