  • 58-1/2 in. Long Aluminum Innerside Truck Box with Gearlock (Bright)


    What is the recommended attachment method for this product. All descriptions state that a mounting kit and support legs are included but there are no further details on the installation. Will I need to drill into the bed or rails or is it a clamp or bolted hook application?
