UWS underbody tool boxes provide unbeatable storage and security for your items under the bed of your truck or trailer. The box conveniently mounts underneath the bed of a flatbed truck, dump truck or trailer, leaving more space on top of the bed for other cargo. Each box features a corrosion-resistant aluminum construction, heavy-duty cable door supports and a stainless steel locking system -- all to keep your equipment and valuables safe and easily accessible whenever needed. Each UWS underbody tool box is constructed from extra-thick aluminum for increased structural strength. The tub is welded together into a single piece for weather resistance and to easily hold heavy tools and other items. The door features aircraft-grade stainless steel cables, rated to support up to 1,000 lbs., ensuring reliable strength and door operation. The locking mechanism of this underbody truck tool box provides excellent security for your items, featuring a stainless steel, key-operated T-handle. Stainless steel construction supplies the lock with long-lasting corrosion resistance, and the door also has a MicroSeal gasket, blocking moisture, dust and insects from getting inside and damaging your valuables. The door also opens a full 90 degrees for easier access. UWS truck tool boxes are available in multiple sizes to accommodate any storage need. Like all UWS products, each one is proudly assembled right here in the USA for style and long-lasting dependability.

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.

UWS | Tough. Reliable.
The package includes one underbody tool box and two keys. Hardware for installation is not included; you must purchase your own fasteners separately.
The tool box may be mounted on various truck types and chassis styles. However, the manual does not specify which models or years are compatible. Contact your local truck up-fitter or equipment dealer to confirm fitment for your specific vehicle and to obtain the correct mounting brackets.
Yes. Mounting brackets are not included with the tool box. You must contact your local truck up-fitter or equipment dealer to obtain mounting brackets. Brackets must be equal to or thicker than 1/4" steel, and the underside of the tool box must be supported.
You must purchase your own hardware. The manual provides general torque specifications for common bolt sizes: M6/1/4" bolts at 3 ft-lbs, M8/5/16" bolts at 7 ft-lbs, M10/3/8" bolts at 16 ft-lbs, M12/7/16" bolts at 28 ft-lbs, and 1/2" bolts at 28 ft-lbs. If you purchase hardware with its own torque specifications, use those instead of the general guidelines.
Before drilling, check under your vehicle to ensure the drill location does not puncture, cut or obstruct any brake lines, fuel lines, electrical wires, fuel tanks or other components. Take precaution that all fasteners near the fuel tank do not create the possibility of fuel tank puncture or other damage during a collision.
Do not use this tool box for storing or transporting flammables, explosives, hazardous materials or hazardous waste, such as containers of gasoline, solvents, gun powder, dynamite, propane tanks, acetylene tanks and cutting torches. The tool box is designed for tools and general equipment only.
Yes. Never exceed the vehicle manufacturer's recommended capacity. The manual does not specify the tool box's own capacity rating; consult your vehicle's owner manual or contact CURT for the maximum load limit.
No. Do not interfere with factory-installed safety equipment during installation. Ensure the tool box and mounting brackets do not obstruct or damage any OEM safety systems, sensors, or components.
Use mild automotive detergent to clean the product. Do not use dish detergent, abrasive cleaners, abrasive pads, wire brushes or other similar products that may damage the finish. For polished, gloss and other smooth finishes, polish may be used to clear small scratches and scuffs.
Yes. Treat or seal all fasteners and exposed metal in any holes drilled in the vehicle to prevent corrosion. This protects against rust and extends the life of the installation.
