The ORIGINAL Tailgate Gap Cover: ROK BLOCK™

ROK BLOCK™ tailgate gap cover bridges the gap between the truck bed and tailgate, preventing the loss of materials such as mulch, sand and rock.




No more cleaning out debris from the tailgate gap. When the tailgate is closed ROK BLOCK™ folds into the tailgate gap, doubling as a tailgate seal. To keep out debris from entering in through the sidewalls install a Tailgate Seal with Taper Seal®.

Adheres to vehicle using 3M ST1200 adhesive. 10 minutes installation.

ROK BLOCK comes in two different width - 4.25" and 7".

For Nissan Frontier and all pickup trucks overseas, install ROK BLOCK XL.
