BackRack 2007+ Chevy/GMC Silverado Sierra HD Only Low Profile 21in Drill Hardware Kit

Our new LOW PROFILE DRILL Hardware Kit is available for select late model fullsize trucks. These require you to drill two holes through the top of the bed rail for installation. If you must have the Toolbox sitting at bed rail height this is the option. Four carriage head bolts secure the assembly allowing you to place the Toolbox at a low profile using existing clamps that came with the Toolbox. Drill if you must. Not compatible with TONNEAU COVER ADAPTER Brackets.
