Transform your work vehicle into a powerhouse of organization and security with the UWS steel underbody tool box. Crafted with meticulous attention to detail, UWS tool boxes provide an unrivaled storage solution for your professional-grade tools and equipment. One of the standout features of our steel underbody tool box is its adaptability. Whether your vehicle demands mounting above or below flatbeds, dump trucks or trailer bodies, this toolbox seamlessly integrates into your setup, offering convenience and durability. It boasts the structural integrity to endure heavy loads and challenging environments, featuring extra-thick, 14-gauge steel. But durability is only one aspect of the equation. The sleek matte black powder coat finish not only adds a touch of sophistication to your vehicle's aesthetic but also serves as a formidable shield against corrosion and scratches, ensuring that your tool box maintains its pristine appearance and functionality over time. Convenience and accessibility are paramount when it comes to professional tools, and our steel underbody tool box delivers on all fronts. Equipped with a 90-degree opening door and stainless steel cables, accessing your tools has never been easier or more secure. Moreover, we understand the importance of safeguarding your investments. That's why our tool box is designed with reliable security features, including a lockable T-handle and a MicroSeal? gasket, to protect your tools from theft as well as moisture, dust and dirt. Designed in the USA and imported from Mexico, this UWS tool box embodies the highest standards of quality and reliability. Trust in its robust construction and innovative design to keep your tools safe and secure, no matter where your work takes you.

UWS designs and builds heavy-duty truck tool boxes and storage for tradespeople and truck owners. The line covers crossover and side-mount boxes, chest boxes, underbody boxes, transfer tanks and dog boxes. Every aluminum box is designed, fabricated and welded in Perry, Florida, with construction aimed at job-site abuse, road vibration and daily use.
UWS is a leading manufacturer and designer of truck tool boxes and truck accessories, and a Lippert brand. The company's focus is narrow and deliberate: storage that stands up to being opened and slammed shut dozens of times a day, loaded past what looks reasonable, and left outdoors in whatever weather the job brings. Its customers are electricians, plumbers, contractors, farmers, outdoorsmen and truck owners who treat a pickup as a working tool rather than transport.
The catalog covers the full range of bed storage. Crossover boxes sit across the bed behind the cab in single-lid, gull-wing, secure-lock and low-profile styles, so there is a fit whether the priority is capacity, rear visibility or working under a tonneau. Side-mount boxes mount along the bed rails and keep the bed floor free for cargo, while underbody boxes tuck beneath the frame rails of service bodies and flatbeds.
Beyond the bed, UWS makes portable chest boxes that move between vehicles and the shop, transfer tanks and combination tank-and-toolbox units for crews working away from fuel supply, and insulated, ventilated dog boxes for hunters and handlers.
Manufacturing sits at the centre of the brand's identity. Every UWS aluminum tool box is designed, fabricated and welded in Perry, Florida, by tradespeople with decades of experience, and the company's Rooted in Trades initiative is built around that connection to skilled manual work. Boxes use heavy-gauge aluminum, continuous welds at the seams, weather stripping to seal against rain and dust, and locking systems intended to resist tampering. The practical result is storage that keeps tools dry, organized and where they were left.
