Extang 80450 Endure ALX Hard Folding Tonneau Cover Chevrolet Silverado/GMC Sierra 1500/2500/3500 14-19 6'6"
Extang Endure ALX
The Extang Endure ALX combines a flush-mounted profile with EnduraShield construction and one-handed operation to deliver durable, low-profile truck bed protection.
The cover uses four patented EnduraShield TPO panels, an automotive-grade polymer that resists impact, abrasion, and UV exposure. Each panel is reinforced by a robust aluminum frame that provides exceptional structural rigidity and supports up to 500 lb of evenly distributed weight. The alloy frame features a matte black EnduraCoat finish with textured polymer hinge caps for a seamless appearance.
Extruded weatherproof seals at every seam prevent moisture intrusion and help protect cargo from the elements.
At the tailgate, the cover employs the Secure Rotary Latch System for intuitive, one-handed operation: a simple twist-and-lift to open, with automatic locking when closed against the bed rails.
The cover provides 2/3 bed access with integrated nylon buckle straps to limit movement while driving, and it folds flat against the cab for full-bed access using built-in prop rods.
