UWS utility chest boxes provide unbeatable storage and security for your items, whether in the shop, at home or on the job. Each box features a corrosion-resistant aluminum construction, a stainless steel locking system, a patented RigidCore foam-filled lid and integrated tool storage -- all to keep your equipment and valuables safe, well-organized and easily accessible whenever needed. Each UWS tool box and storage 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 foam core, sandwiched between two aluminum plates. This core greatly increases the rigidity of the lid and helps prevent bending and warping, making operation very smooth. The locking mechanism of the UWS truck tool box provides excellent security for your items, featuring stainless steel, key-operated paddle handles. Stainless steel construction supplies the locks with long-lasting corrosion resistance, and they feature an internal connecting rod that allows the lid to be opened from either side of the truck. For solid protection against the elements, 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 utility chest 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 utility chest box and two keys. A mounting hardware kit (part #003-CBOXMK) may or may not be included depending on the model. If the hardware kit is not included, you will need to purchase your own hardware: two 5/16" or M8 bolts, four washers and two lock nuts.
The chest box mounts to truck beds with raised ribs, which serve as alignment points for the two mounting locations. If your truck has a plastic drop-in bed liner, it may need to be trimmed or cut for proper attachment. Before drilling, you must verify that the drill location does not puncture brake lines, fuel lines, electrical wires, fuel tanks or other critical components underneath the truck bed.
You will need: a drill, 11/32" drill bit, 1/2" drill bit, ratchet, socket set, tape measure, and level. If you are using the mounting hardware kit #003-CBOXMK, follow the instructions included with that kit. If you are purchasing hardware separately, you will also need two 5/16" or M8 bolts, four washers and two lock nuts.
Before drilling, check underneath 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 special precaution that fasteners near the fuel tank do not create the possibility of fuel tank puncture or damage during a collision. If your truck has a plastic drop-in bed liner, it may need to be trimmed or cut for proper attachment.
1. Place the chest box in the desired location and check that the lid operates properly. Select two mounting points in the bottom of the chest box aligned with the raised ribs in the truck bed. 2. Drill through the chest box and truck bed with an 11/32" drill bit. If using the hardware kit #003-CBOXMK, enlarge the truck bed holes with a 1/2" drill bit and follow the kit instructions. Otherwise, install two 5/16" or M8 bolts, four washers and two lock nuts. 3. Tighten all fasteners to the recommended torque values. Use silicone-type caulk to seal any open areas around the washers to prevent water seepage. 4. Adjust strikers if needed and lubricate them and the locks periodically.
Yes, drilling is required. You must drill through the chest box and truck bed using an 11/32" drill bit. If you are using the mounting hardware kit #003-CBOXMK, you will also need to enlarge the holes in the truck bed with a 1/2" drill bit. If your truck has a plastic drop-in bed liner, it may need to be trimmed or cut for proper attachment.
The recommended torque specification for 5/16" bolts is 7 ft-lbs. This is a general guideline. If you purchase hardware separately, use the torque specifications provided with that hardware instead.
The recommended torque specification for M8 bolts is 7 ft-lbs. This is a general guideline. If you purchase hardware separately, use the torque specifications provided with that hardware instead.

Yes. Never exceed the vehicle manufacturer's recommended capacity. Consult your vehicle's documentation or your dealer for the specific weight limit.
After installation, ensure all knobs, bolts, screws, straps and locks are firmly secured. Verify that the lid operates properly. Check that all mounting hardware is tight and inspect all components for signs of wear, corrosion and fatigue. Periodically re-tighten and inspect all components before every trip.
Periodic inspections should be performed to ensure all mounting hardware remains tight. Ensure all knobs, bolts, screws, straps and locks are firmly secured before every trip, and periodically re-tighten and inspect all components for signs of wear, corrosion and fatigue.
For polished, gloss and other smooth finishes, polish may be used to clear small scratches and scuffs. Mild automotive detergent may be used to clean the product. Do not use dish detergent, abrasive cleaners, abrasive pads, wire brushes or other similar products that may damage the finish. Periodically lubricate the strikers and locks to ensure optimum performance.
After tightening all fasteners, use a silicone-type caulk as needed to fill in any open areas around the bolt flat washer or bonded washer inside the chest box to prevent water from seeping in.
Treat or seal all fasteners and exposed metal in any holes drilled in the vehicle to prevent corrosion. This is especially important for fasteners near the fuel tank.
Chest boxes come with adjustable strikers. If the strikers are ever out of alignment, simply loosen, adjust and re-tighten them to ensure proper lid operation.
The chest box mounts to truck beds with raised ribs for alignment. If your truck has a plastic drop-in bed liner, it may need to be trimmed or cut. Verify that the drill location does not puncture brake lines, fuel lines, electrical wires or fuel tanks before installation.
