UWS utility chest boxes provide unbeatable storage and security for your items, whether in your vehicle, in the shop, at home or on the job. 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 particular tool box is designed to offer a perfect fit for the UWS cargo carrier #UWS-CARRIER. It can also be used as a standard storage chest box for a variety of applications. It is constructed from extra-thick aluminum for increased structural strength, and the tub is welded together into a single piece to make it completely waterproof. 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 cargo carrier 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 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. Like all UWS tool boxes, this product is proudly assembled right here in the USA for style and long-lasting dependability.
