UWS topside truck tool boxes provide unbeatable storage and security for your items in the bed of your truck and on the jobsite. Each box features a corrosion-resistant aluminum construction, heavy-duty aircraft cable door supports and a stainless steel locking system -- all to keep your equipment and valuables safe and easily accessible whenever needed. Each UWS truck side 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 door features aircraft-grade stainless steel cables, ensuring reliable strength and door operation. The locking mechanism of this truck side tool box provides excellent security for your items, featuring a stainless steel, key-operated T-handle. Stainless steel construction supplies the lock with long-lasting corrosion resistance, and the door also has a MicroSeal gasket, blocking moisture, dust and insects from getting inside and damaging your valuables. The door also opens a full 90 degrees for easier access. UWS truck tool 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 (NOTE: This product is heavily packaged for parcel shipping).
