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, when using a truck bed cap or cover, install our patented
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".
