UWS trailer tongue boxes provide unbeatable storage and security for your items wherever you tow your trailer. Each box features a corrosion-resistant aluminum construction, a stainless steel locking system and a patented RigidCore foam-filled lid -- all to keep your equipment and valuables safe, well-organized and easily accessible whenever needed. This trailer tool box is designed to be mounted on an A-frame trailer tongue. Each UWS trailer 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 lid features a patented RigidCore foam-filled design, sandwiched between two aluminum plates. This greatly increases the strength of the lid and helps prevent bending and warping, making operation very smooth. The locking mechanism of the UWS trailer tool box provides excellent security for your items, featuring a stainless steel, key-operated paddle handle. Stainless steel construction supplies the lock with long-lasting corrosion resistance, and the lid also has a MicroSeal gasket, blocking moisture, dust and insects from getting inside and damaging your valuables. The lid also opens a full 90 degrees for easier access, and it is equipped with self-opening struts for convenient operation when your hands are full. UWS trailer 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 (NOTE: This product is heavily packaged for parcel shipping).

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 the trailer tongue box and one key. Mounting hardware is not included. CURT recommends purchasing a minimum of two square 3/8" U-bolts with nuts and washers separately to secure the box to your trailer tongue.
The manual shows the box is designed for single-tube tongues and Y-style yoke configurations. However, the manual does not specify compatible tongue diameters, trailer models, or other specific fitment details. Contact CURT at 877.287.8634 or consult your dealer to confirm compatibility with your specific trailer.
You will need: a drill, drill bit set, ratchet, socket set, and tape measure. Mounting hardware (U-bolts, nuts and washers) is not included and must be purchased separately.
CURT recommends a minimum of two square 3/8" U-bolts with nuts and washers. These are not included and must be purchased separately.
Carefully place the box in its intended mounting location. Ensure it is centered left to right on the tongue. Check that the lid will not contact anything when opened, and verify that the trailer's leveling crank (if present) will not hit the box when rotated. Once positioned correctly, mark the mounting locations on the bottom of the box using proper spacing for your U-bolts.
Before drilling, ensure your drill locations will not puncture, cut or obstruct any brake lines, fuel lines, electrical wires, or fuel tanks inside the box or tongue. The manual recommends installing hardware from the underside to help prevent damage. If you are unsure about internal components, consult your dealer.
Drill holes in the front and rear of the box, spaced properly for your U-bolts. Holes must be drilled through the aluminum angle in the bottom of the box for added strength. The manual provides diagrams showing drill mark locations for single-tube and Y-style yoke configurations.
The general torque specification for 3/8" bolts is 16 ft-lbs. However, the manual notes that if you purchase hardware separately, use the torque specifications provided with that hardware, as they may differ. For U-bolts specifically, consult the hardware manufacturer's instructions.
Position the U-bolt around the trailer tongue and up through the bottom of the box. Secure it with washers and nuts (not included). Tighten all fasteners to the appropriate torque specification for your hardware size. The manual recommends installing hardware from the underside to help prevent damage.
Do not use this box for storing or transporting flammables, explosives, hazardous materials or hazardous waste, including gasoline, solvents, gunpowder, dynamite, propane tanks, acetylene tanks, or cutting torches. Additionally, never exceed the vehicle manufacturer's recommended capacity.
Ensure all knobs, bolts, screws, straps and locks are firmly secured before every trip. Periodically re-tighten and inspect all components for signs of wear, corrosion and fatigue. With the box installed, perform periodic inspections to ensure all mounting hardware remains tight.
Use mild automotive detergent to clean the product. Do not use dish detergent, abrasive cleaners, abrasive pads, wire brushes or similar products that may damage the finish. For polished, gloss and other smooth finishes, polish may be used to clear small scratches and scuffs. Treat or seal all fasteners and exposed metal in any holes drilled to prevent corrosion.
Ensure all knobs, bolts, screws, straps and locks are firmly secured before every trip. Periodically re-tighten and inspect all components for signs of wear, corrosion and fatigue. The manual does not specify an exact interval, but recommends regular checks to keep the box secure.
