Digital laser measurements of interior surfaces offer a consistently perfect fit. A patented tri-extruded composition allows for a rigid core for strength while offering surface friction to the carpet, as well as tactile feel to the surface. The FloorLiner advanced surface design has channels that carry fluid and debris away from shoes and clothing into a lower reservoir. The lower reservoir uses additional channeling to minimize fluid movement while driving. Once fluids become trapped in the reservoir they are easily removed from the WeatherTech FloorLiner over the door sill.
