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Hinge® allows trailer owners to easily adjust an integrated torsion bar, eliminating the need for dangerous and outdated cable spring systems.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

Adjusting the tension on ramp doors with cable systems can be tiring and dangerous, but the Infinite Hinge’s integrated torsion bar allows users to simply adjust the ramp door tension with a socket wrench. Turn the tension bolt clockwise to increase tension, and counterclockwise to ease the tension.
