TONNEAU COVER ADAPTORS BACKRACK(TM) does not make Tonneau Covers but we have created an accessory called the Tonneau Cover Adaptor Kit (TCA). This kit allows you to install certain types of Tonneau Covers with BACKRACK(TM) and Safety Rack Cab Guards. CLAMP TO THE RAIL TONNEAU COVERS Backrack(TM) Cab Guards sit on the bed rail at the front of the truck bed, over the front Stake Pockets. Tonneau Covers that encroach on this area are generally not compatible with BACKRACK(TM) products. Certain Tonneau Cover manufacturers clamp their covers to the inside rail of the truck bed, exposing the area above the Stake Pockets. These type of Tonneau Covers are compatible with BACKRACK(TM) Cab Guards. HOW DO THE TONNEAU COVER ADAPTORS WORK? The TCAs simply lift your BACKRACK(TM) Cab Guard up by one or two inches depending on your trucks make, model and year. BACKRACK(TM) Cab Guards need that increase in height to clear the Tonneau Cover. The TCAs also include extended Stake Pocket Bolts (SPBs) to replace the SPBs that came with your BACKRACK(TM) Cab Guard originally. These extended SPBs are required to accommodate the increased height. IS YOUR TONNEAU COVER COMPATIBLE? We have created a Tonneau Cover Compatibility Chart listing covers that are compatible with BACKRACK(TM) Cab Guards. Before purchasing a Tonneau Cover, be sure to refer to this Chart. Click on the icon above to view. Some covers may require slight modification and are listed on the Chart along with the fully compatible and incompatible Tonneau Covers.
