ESI Tailgate Seals Editorial Review

ESI ROK BLOCK Tailgate Gap Cover is an effective solution to keep out dust, moisture, and debris from entering the truck bed. It is easy to install and comes in two sizes, 4.25" and 7", to fit a variety of truck models. The adhesive tape used to install the ROK BLOCK is strong and permanent and is not recommended to be removed frequently. The product comes with a primer pen to prepare the surface before installation. It works well on trucks with factory bed liners, and customers have reported positive results even after hauling heavy objects. The ROK BLOCK may require some trimming to fit perfectly, and a roller tool can be used to seal along the bed grooves.
