High Side Truck Tool Box
Maximize organization and productivity without sacrificing bed space.
Maximize organization and productivity with our high-capacity High Side Truck Tool Box. These side-mount truck tool boxes will never rust and they are half the weight of steel high-side boxes. The body of the box is made from 1/8-inch military-grade aluminum with high-strength doors that are 1/10-inch thick. The advanced rain gutter design diverts water away from the watertight seal. The combination of the rain gutter and weatherstripping ensures that your tools and supplies are protected from the elements. High Side Truck Tool Boxes make it easy to load and unload your tools because you don't have to bend down or step up to access them. Our side-mount truck boxes are available in a variety of sizes and come with our lifetime warranty.
