PowerLift Doors are built using the best, most up-to-date, and user friendly technology available. Each of our hinges use 1" stress-proof shafting, rated at 100,000 lbs shear strength.
Our no maintenance greaseless bushings are a composite material, consisting of bonded layers of a steel backing and a porous bronze matrix, impregnated and overlaid with PTFE bearing material. We have personally tested these bushings to over 86,000 cycles, while measuring less than .003? of wear. To put that in perspective, you could open and close your door every day for 235 years and the hinges would still be going strong! Other manufacturers are forcing their customers to climb a ladder twice a year to manually grease all their hinges. Totally unnecessary with a PowerLift Door!
Every PowerLift door features upper cylinder mounts with a double post design, the same vigorously tested bushings in our hinges and cylinders, and a non-twist design on our posts so we don’t have to “band-aid” our cylinders to compensate for a poor design like our competitors. Our innovations allow us to offer a lifetime warranty on our door structure, no one else does that. Only PowerLift…. Always the Innovator, Never the Imitator!!!
