The Endure ALX features four patented EnduraShield TPO-coated panels, forming a seamless yet incredibly strong bed cover assembly. Each 1/2-inch thick panel is crafted with a lightweight aluminum frame for exceptional structural rigidity, enough to support 500 lbs. of evenly distributed weight, while maintaining remarkable resistance to scratches, dents, and unsightly UV-related fading. The cover's perimeter frame features a matte black powder coat finish with hard polymer corners and hinge caps, reinforced with extruded weatherproof seals at every seam to protect the bed and your cargo from the elements. At the tailgate, the Endure ALX utilizes a specially-engineered Secure Rotary Latch System, an industry-first and Extang exclusive. Its intuitive design allows one handed operation with a simple twist-and-lift motion and automatically latches closed for exceptional security. And when maximum bed space is needed, the Endure ALX fully folds up to the cab allowing full bed access in seconds, making it as easy to live with as it is to operate.
