While the Solid Fold ALX might look like just another hard folding bed cover, its feature-packed design proves to be anything but average. Built from lightweight, 1 Inch thick EnduraShield panels, the Solid Fold ALX from Extang resists dents, scratches and UV induced fading better than typical aluminum or fiberglass panels. Despite being lightweight, the structure is remarkably strong- capable of supporting 600 Pounds of evenly distributed weight. That's incredibly tough by any standard. Our Secure Rotary Release Latching System makes the Solid Fold ALX secure yet amazingly easy to operate, day in and day out. The Solid Fold ALX features an attractive Matte Black Textured finish applied over an aircraft-grade aluminum frame constructed to deliver unrivaled bed and cargo protection.
