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 highly secure stainless steel locking system, a 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 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 a stainless steel, key-operated paddle handle. Stainless steel construction supplies the lock with long-lasting corrosion resistance. 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.
