Each extremely strong 1" hinge has four layers of tough vinyl as internal reinforcement.
For added strength and durability in a high stress area, each hinge is double stitched to the top vinyl and put through strenuous testing. The test includes being hooked up to an automatic arm with a SUPERLIFT2™. The cover was then lifted on and off over 8000 times with no significant wear to the hinge.
These hinges are also manufactured for easy compatibility to the many of today's cover removal systems.
