The UWS Single Door Underbody Toolbox mounts above or below your flatbed, dump truck or trailer body to provide extra storage for your tools. The underbody toolbox is made from an extra rigid aluminum, and welded into a single piece tub to add strength. This also adds no excess points for water and debris to get inside. To help keep moisture and debris from getting inside, UWS uses a MicroSeal gasket inside the toolbox door to form a tight seal when closed.

The toolbox door opens downward 90 degrees to allow full access along with providing a handy platform. The cables that support the door when opened are aircraft-grade stainless steel, and can hold up to 1,000 lbs. Multiple box sizes are available with a key-locking, stainless steel T-handle. The stainless steel construction ensures a highly durable locking function that will resist corroding. UWS products are made in the USA with high-quality components, and backed by a limited lifetime warranty.
