UWS truck side tool boxes provide unbeatable storage and security for your items in the bed of your truck. Each box features a corrosion-resistant aluminum construction, a highly secure 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. Each UWS truck 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 2 aluminum plates. This greatly increases the strength of the lid and helps prevent bending and warping, making operation very smooth. This particular truck tool box features a low profile for a more streamlined look and to match UWS low-profile crossover tool boxes. The locking mechanism of the UWS truck side tool box provides excellent security for your items, featuring a stainless steel, key-operated paddle handle for long-lasting corrosion resistance. For solid protection against the elements, the lid also has a Micro-Seal gasket, blocking moisture, dust and insects from getting inside and damaging your valuables. The lid also opens to nearly 90° for easier access, and it is equipped with self-opening struts for convenient operation when your hands are full.
