The Buyers Products Diamond Tread Aluminum Pick-Up Contractor Truck Tool Boxes optimize the storage space on your pick-up truck. Measuring 21” tall and 13.2” deep, these truck boxes offer two storage tiers for your tools and equipment, while leaving ample room in your truck bed for oversized cargo. Constructed from durable 0.056 in. thick diamond tread aluminum to resist corrosion, these boxes are built for the long haul. Offering accessible storage while out on the road, the upper cabinet has a shelf to store larger oversized equipment and the 2-bottom drawers provide additional organization. Each drawer includes adjustable dividers for organizing gear. The external rain gutter and weather-resistant seal protect gear from moisture and grime, while the locking, stainless steel compression latches provide theft protection. Gas shocks ensure the upper flip-up door opens smoothly and stays open. Mounting hardware is included. Choose a no-drill mounting option with the included J-hooks and protective side-rail pads. The Buyers Products Pick-Up Contractor Tool Boxes provide extra storage while still leaving ample room in your truck bed for sheet goods and larger cargo.
