Show Your Customers that You Care. Featuring "The Name" in interior protection products, Slip-n-Grip. Two distinctly different plastics (a slippery top layer, a gripping bottom layer) are laminated together to form a unique, patented two-ply seat cover. The Slip-n-Grip seat cover clings to the seat while allowing a service technician or porter to freely slip in and out of the vehicle without shifting the protective cover. This is the brand Original Equipment (OE) manufacturers rely on to keep their vehicles clean during the manufacturing process. Available in a dispenser box of 250 or a handy roll of 250.
