Box Covers

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 lbs. of evenly distributed weight. That's incredibly tough by any standard., Secure Rotary Release System uses a simple “twist & lift” function to open and close the cover without the use of tailgate clamps. Durable 1-inch thick EnduraShield panels resist dents, scratches, and UV induced fading while also being capable of supporting 600 lbs. of evenly distributed weight. Hard polymer rubber corners, hinge caps, and snap-on perimeter seals keep out virtually all elements. Attractive Matte Black Textured finish applied over an aircraft-grade aluminum frame. Jaw Grip clamps for easy installation. Maximum Strength 5-year Warranty.

While the Extang Solid Fold ALX might look identical to our popular Solid Fold 2.0, it comes with one key difference—the addition of our proprietary Secure Rotary Release Latching System. This system is also found on our low-profile Endure ALX and soft-folding Trifecta ALX, offering easy one-handed operation—simply drop the tailgate, twist, and lift. Closing the Extang Solid Fold ALX is just as easy—the cover's Secure Rotary Release Latching System automatically latches when shut against the bed rails. Aside from our upgraded rotary latch system, the Solid Fold ALX features the same premium build quality as the Solid Fold 2.0, including proprietary 1-inch thick EnduraShield TPO panels to resist dents, scratches, and UV-induced fading. Reinforcing these panels is a lightweight, EnduraCoat-finished aluminum frame with dual-pivot MaxHinges. Despite the cover’s lightweight design, it’s remarkably strong—capable of supporting 600 pounds of evenly distributed weight. If weather resistance is a concern, Extang has you and your truck bed covered. Exclusive hard polymer rubber corners, hinge caps, and snap-on triple-fin perimeter seals prevent moisture intrusion from any angle, keeping your cargo clean and dry. Installing the Solid Fold ALX Tonneau Cover is quick and easy using Extang’s proprietary, tool-free Jaw-Grip clamps and bolt-on rotary latch strikers. If full bed access is required, the cover is removable in seconds without any tools. Extang is a RealTruck® brand.
