Infinite Hinge®

The Infinite Hinge® allows trailer owners to easily adjust an integrated torsion bar, eliminating the need for dangerous and outdated cable spring systems.

Say good-bye to cable systems with our revolutionary torsion hinge

Ramp door cable systems present problems to manufacturers and owners. Adjusting the tension on cable systems can be tiring and dangerous. The Infinite Hinge's integrated torsion bar allows users to simply adjust the tension settings on their ramp door with a socket wrench. Simply turn the tension bolt clockwise to increase tension, and counterclockwise to ease the tension. Adjustments have never been so easy!

Quick Facts

The Infinite Hinge's revolutionary engineering allows the customer to self-adjust the torsion bar from 0-45° or 80 to 100 pounds in order to accommodate for add-ons, ATP, etc.

Customers can simply use a socket wrench to make adjustments to the cargo door without calling a dealer or worrying about dangerous cables. Infinite Hinge's torsion bar takes care of the job quickly and easily.
