Top Mount Box

Top Mount Truck Tool Boxes

Our top mount truck tool boxes (also called topside boxes or rail boxes) bolt directly to your truck bed rails, keeping tools above the bed floor and the bed itself clear for cargo.

Available in aluminum or steel, with single or double top-hinged doors, gas springs, and dolphin-tail T-handle locks. Standard widths and custom sizes both available.

Topside tool boxes for flatbed trucks, service bodies, and pickup rails.
