Buyers Products Diamond Tread Aluminum Topsider Truck Box provides a convenient and secure way to store your tools. The box mounts on your truck bed rails, keeping your tools easy to access and saving valuable storage space in the bed. These truck tool boxes are ideal for pick-up trucks, flatbed trucks, and service utility bodies. Each truck box is constructed from 0.100 in. thick aluminum with dual, recessed drop doors. Corrosion-resistant diamond tread aluminum is durable but lightweight. A continuous hidden hinge and weather-resistant seal keep moisture and dirt away from your equipment. Aircraft-grade cables keep the door from slamming and damaging the hinge or doors. A locking die-cast T-handle compression latches create a tight seal and help deter theft. Mounting hardware included. Choose a no-drill mounting option with the included J-hooks and protective side-rail pads.
