Diamond plate, also known as checker plate or tread plate, is a regular pattern of raised diamonds on one side which combines the looks of toughness and durability.
Sharp and Clean! In 1980 Highway Products invented the 5th Wheel Tool Box because customers wanted a box that they could place against the truck cab and still be able to open it.
The back of the box is notched so the back of the lid has a place to go as you open it. This space-saving flush mount truck tool box secures to the bed of your truck and sits flush with the side rails.
The low profile design increases visibility and allows your fifth wheel to swing freely without hitting the lid during sharp turns.
Constructed from 1/8 inch thick marine grade aluminum, this corrosion-free box keeps your tools secure and dry.
