Lift Cables

OVERVIEW

Lift cables wrap around the driveline as it turns, providing the lifting force necessary to raise the bifold door. Our proven lift systems are more reliable, last longer, and are safer than other lift options.

We use specialized cables with a fine weave and nylon core that are more flexible and less susceptible to damage. These cables have 18 braids with 7 strands per braid. Common competitor door cables have 7 braids, with 19 strands per braid. This results in a stiffer cable that wears out faster.

Another advantage of the Diamond Doors cable lift system is our simplified design. With almost no moving parts, and a system that prevents the cables from overlapping (which is the primary cause of cable failure), it’s built for reliability and longevity. Our cables wrap consistently, every time.

Our 10:1 safety factor ensures that even if one, or multiple cables fail, your door will remain safely in place even while open. The added cables also help to better distribute the loads on the building.

Finally, cables are a low maintenance lift system option. Because they have their initial stretch upon installation, they rarely need tensioning throughout their lifespan. When tensioning is required on a Diamond door, cables can easily be adjusted at ground level. We provide thorough instructions on how to do this in our owners manual.
