"From tireless engineering and a relentless pursuit for perfection comes a low-profile bed cover designed to function like no other - the Endure ALX from RealTruck. With a flush-mounted design, the Endure ALX creates a seamless, polished exterior appearance when closed while delivering highly functional full-bed access when open. 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. Best of all, RealTruck backs the Endure ALX with a limited 5-year warranty, and the installation is so simple it can completed in your garage or driveway with a few simple tools in about half an hour."
