The original tailgate gap cover since 1999, "ROK BLOCK" bridges the gap between the truck bed and tailgate, preventing the loss of materials such as gravel, dirt, mulch and sand. For drop-in bed liners ROK BLOCK installs under the liner. Doubles as a tailgate seal, for the tailgate gap, when using a truck bed cap or cover. TIP: If you have a truck bed cap or cover and occasionally use your truck for transporting loose material then install ROK BLOCK over the tailgate gap area and install patented Ultimate Tailgate Seal with Taper Seal on the sidewalls.
