BackRack 21-inch toolbox brackets let you mount over-the-rail style toolboxes flush against a BackRack without drilling into the truck bed. The standard 21-inch pair removes the gap between toolbox and rack, installs with original hardware replacement, and includes a durable powdercoat finish and a limited lifetime warranty. An optional 31-inch option is available for different toolbox sizes.
