BackRack 21-inch toolbox bracket pair replaces standard rail-mount hardware so an over-the-rail toolbox can sit flush against the BackRack without drilling into the truck bed. The 21-inch set eliminates the gap between toolbox and rack, includes two powdercoated brackets for durability, and is backed by a limited lifetime warranty. Fits common BackRack toolbox configurations.
