Made of contractor-grade 0.100 mil diamond tread aluminum, this toolbox offers large 12" tall openings and recessed door frame for easy access to spacious storage area. Features include stainless steel folding T-handles with lock, full-length continuous hinges, and aircraft cable door retainers designed for superior strength that won't scratch the box or its contents. Weather stripping is mounted to the box and shielded by the beveled door, to minimize sun exposure and prolong the life of the gasket. J-bolts fasten under bed lip, so there's no drilling in the side rails. Mounting hardware and instructions included.
