Features
Built for a crossover toolbox
This kit is the choice when a crossover toolbox spans the bed behind the cab, so the rack and the box share the front of the bed.
Toolbox slides forward
The toolbox rides on top of the brackets and can be pushed forward toward the cab, which saves usable bed length.
Toolbox clamps not needed
The toolbox is fastened to the tops of the brackets with screws or bolts through the box floor, so the clamp hooks that came with the toolbox can stay in the drawer.
Sized for 21" and 31" boxes
Choose the bracket length that matches your toolbox; 21" and 31" versions are offered.
Heavy-duty powder coated steel
Steel brackets in a powder coat finish resist corrosion and match the color of your BackRack frame.

About BackRack
BackRack builds steel headache racks that stand between the truck bed and the cab, guarding the rear window and cab from cargo that slides forward. The racks are made for trucks that work hard during the week and still need to look sharp when the job is done.
Every BackRack frame mounts to the bed through a truck-specific installation kit. Separate kits let the rack live alongside a crossover toolbox, a bedliner or a tonneau cover that clamps to the inside of the bed rail.
Because a BackRack sits low behind the cab, the truck still fits in a home garage and multi-level parking. Light brackets, tool holders, side rails and a rear bar turn the same frame into a platform for lights, long loads and gear, and the steel is finished in a powder coat applied in house.
