Husky Liners Classic Style rear cargo liners are custom fit floor mats with a raised lip made to fit the complex contours of your specific vehicle's carpet area. Husky Liners make custom fit Classic Style rear cargo liners with a patented rubberized thermoplastic material which is guaranteed not to crack or break. The Husky Liners Classic Style rear cargo liners design of raised embossing keep spills on the floor mat and the mess off the carpet. To help prevent your Classic Style rear cargo liners from sliding around, all Husky Liners are designed with their patented STA-PUT NIBS (SPiN) technology. These anti-slip Nibs, located on the back of the floor liner, grip the carpet and hold the liner in place. The floor liner being kept in place is important, because if your floor liner shifts, your carpet becomes exposed and unprotected. Husky Liners nibs keep your Classic Style rear cargo liners in place without the use of additional fasteners. This also means no holes in your liner which can cause unwanted leakage and ultimately end up damaging to your carpet.
