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 sn owmobile 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.
