UWS crossover truck tool boxes are the tried-and-true 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. This particular box features a slim-line design, providing adequate clearance for truck beds that have extremely limited space between the wheel wells and truck cab. It also 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 add even more strength to the crossover truck tool box, the lid features our patented RigidCore foam-filled design. Layered between two 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 degrees, 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. 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. UWS crossover truck tool boxes make it easy to keep your tools and other items organized, featuring a three-compartment sliding tool tray. Like all UWS products, each crossover truck tool box is proudly assembled right here in the USA for style and long-lasting dependability (NOTE: This product is heavily packaged for parcel shipping).
