The UWS FWB-58-MB 5th Wheel Toolbox is built for truck owners who need secure, accessible storage without interfering with a 5th wheel trailer. Designed with a low-profile build, this truck toolbox provides the clearance needed for safe towing while still offering 6.1 cubic feet of rugged storage space in your truck bed.

Crafted from extra-thick 0.058" aluminum and finished in a sleek matte black powder coat, it’s engineered to handle tough jobs while resisting corrosion. The patented RigidCore™ foam-filled lid adds structural strength and prevents binding, while the dual stainless steel paddle lock handles—connected by a rod—make it easy to open from either side of the truck. Inside, integrated tool organization keeps small items neat and within reach.

The self-opening lid opens to 90° for smooth loading, and a MicroSeal™ gasket protects your gear from dust, moisture, and the elements. Designed to sit inside the truck bed without blocking the rails, this low-profile aluminum toolbox is perfect for use with other accessories or rails. As with all UWS products, it's proudly assembled in the USA and backed by a limited lifetime warranty. Whether you’re hauling heavy loads or hitting the road with a trailer, the UWS 58" 5th Wheel Toolbox gives you the strength, clearance, and security you need—all in a compact, user-friendly package.
