The Buyers Aluminum Barn-Door Underbody Tool Box provides safe and convenient storage without sacrificing space. Designed to mount beneath the body of your truck or work vehicle, this tool box is made from heavy-duty .100-mil polished diamond-tread aluminum. Unlike traditional underbody tool boxes, this box has a ""barn door"" that swings outward to the left rather than downward, providing closer access to the contents. A reinforced door backbone strengthens the integrity of the door and protects the latch mechanism, which is made from stainless steel and has a locking T-handle closure. This tool box also features a 1/2-inch door gasket and a continuous hidden hinge which is designed to be watertight, protecting your tools from rust and corrosion. The door is replaceable and is recessed into the body of the tool box. Made in the USA, this box is available in your choice of sizes. Measure your vehicle before purchasing to ensure the proper fit. * .100-mil bright polished diamond tread aluminum * 1/2-inch automotive-style door gasket * Barn-style door swings out and to the left for easy access * Hidden, waterproof continuous hinge * Stainless steel locking T-handle latch * Mounts beneath vehicle for superior storage
