Store tools and equipment under a truck or trailer with this underbody tool box. Our underbody truck box sets itself apart from the competition with its rugged polyethylene construction, making it completely rust and dent proof. A single piece, rotationally molded design eliminates the need for welds, making the storage box exceptionally strong. Every wall of the storage box is at least 1/4" thick, and the door is double-walled for extra strength and durability. The recessed, 1/2" gasket door is attached with a water tight continuous hinge, which allows it to open a full 180° for unrestricted access to the underbody tool box interior. This underbody storage box has an attractive diamond plate like door, and a black finish that is UV treated to prevent fading. Made in the USA, our underbody tool box is backed by a two year manufacturer warranty. Mounting Brackets Sold Separately.
