|In the quest for the most advanced concept in floor protection available today, the talented designers and engineers at MacNeil have worked tirelessly. The WeatherTech FloorLiners accurately and completely line the interior carpet, giving absolute interior protection. Digital laser measurements of interior surfaces offer a consistently perfect fit. A patent-pending, high-density, tri-extruded (HDTE) material features a rigid core for strength, while adding surface friction to the carpet, as well as a tactile feel to the surface. Advanced surfacing creates channels that carry fluids and debris to a lower reservoir with further channeling to help minimize fluid movement while driving. Once fluids become trapped in the reservoir, away from shoes and clothing, they are easily removed from the WeatherTech FloorLiners over the door sill. No fuss, no muss.
