The National Fleet Underbody Toolboxes are made from chemical-resistant and UV-stabilized polyethylene. These toolboxes are UTAC approved, and are weatherproof. Designed with state of the art tooling, the lid sits in a recess to minimize the potential for water ingress and features a gasket liner to help keep the elements away from your cargo. These toolboxes feature twisting handles that flip up for easy operation with gloves on, and flip down to prevent accidental opening. The handles have an integrated dust cover, and are lockable with key operated locks. The lid opens 180 degrees and sits in a recessed opening to help minimize water penetration. The automotive-grade rubber seal aids in additional weathering protection. The National Fleet Underbody Toolboxes are backed by a 1 year warranty.
