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 can be mounted on a straight-tongue or A-frame trailer, such as a boat trailer or snowmobile trailer. 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.

Original price was $694.95. Current price is $630.95.The EC20422 is a trailer tongue box designed to install on the tongue of a trailer for storage. It features a lid that opens for access. The product is available in various styles, sizes and finishes depending on trailer type.
The EC20422 is designed to install on trailer tongues, but due to trailer style variation, compatibility may vary. The manual notes that mounting hardware is not included and recommends a minimum of two square 3/8" U-bolts with nuts and washers. Consult your dealer if you have questions regarding fitment to your specific trailer.
No mounting hardware is included. Due to trailer style variation, you must purchase a minimum of two square 3/8" U-bolts with nuts and washers separately to secure the box to your trailer tongue.
You will need: a drill, drill bit set, ratchet, socket set, and tape measure. Proper tools will improve installation quality and reduce installation time.
Carefully place the box in the intended mounting location. Ensure the box is centered left to right on the tongue. Verify that the lid will not contact anything when opened, and that the leveling crank on the trailer (if present) will not hit the box when rotated. Mark the mounting locations on the bottom of the box using proper spacing for the U-bolts before drilling.
Drill holes in the front and rear of the box spaced properly for the 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 tongues and Y-style yokes.
Position the U-bolt around the trailer tongue and up through the bottom of the drilled holes in the box. Secure with washers and nuts (not included). Install hardware from the underside to help prevent damage to the product.
Do not use this product for storing or transporting flammables, explosives, hazardous materials or hazardous waste, including containers of gasoline, solvents, gunpowder, dynamite, propane tanks, acetylene tanks and cutting torches. Danger of explosion.
Never exceed the vehicle manufacturer's recommended capacity. Consult your dealer if you have questions regarding the limits of this product.
Before drilling, ensure your drill locations will not puncture, cut or obstruct any brake or fluid lines, electrical wires, fuel tanks, or other critical components. Do not interfere with factory-installed safety equipment. Hardware should be installed from the underside to help prevent damage.
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. Periodic inspections should be performed 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 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.
