Protect and secure your equipment for the long haul with an underbed truck box that offers convenient, easy access on the job site. Buyers Products Diamond Tread Aluminum Underbody Truck Box with Barn Door is crafted with thick diamond tread aluminum and reinforced side-hinged swinging doors that can be mounted to lock on either the right or left side. The "barn door" style allows you to get closer to the contents of the box, so back strain is reduced while you take advantage of the unobstructed space inside with no center post. Boxes come in single- or double-door styles depending on size. A locking, die-cast, compression latch system helps keep your tools safe from weather and theft. Double-door models have a three-point version of the latch to provide a tight seal on the larger sized boxes. The truck box is built to perform with an aluminum continuous hinge and a watertight D-bulb door seal. Available in a wide range of sizes to suit your needs.
