UWS crossover truck tool boxes are the tried-and-true American way of keeping your tools organized, on-hand and fully secure no matter where you and your truck roam. Each UWS tool box is built, from extra-thick aluminum welded into a single-piece tub. This provides the tool box with reliable strength and helps keep the interior sealed off from the elements. Aluminum construction also makes the box highly resistant to corrosion for long-lasting use. To add even more strength to the crossover truck tool box, the lid features our patented RigidCore foam-filled design. Layered between 2-sheets of aluminum, this core greatly increases the structural integrity of the lid to prevent bending and warping and to ensure smooth opening and closing. The lid is able to open to a full 90°, providing better access to tools, equipment and other stored items. It also features self-opening struts to make it easy to open the box when your hands are full. This particular truck tool box features a low profile, meaning the lid is built lower than our standard lid. This provides a better view out the rear cab window and additional clearance for other items in the truck bed, if needed. To keep out moisture, dirt and even insects, the lid is also fitted with a MicroSeal gasket that seals off the inside of the tool box from the outside elements.
