WeatherTech TechFloor is the first modular floor tile system to offer two distinctly different materials molded into one tile. Our revolutionary TwoShot process (patent pending) produces an extremely rugged and low profile polypropylene plastic tile with attractive TractionSquares for wet-or-dry non-slip use. Soft touch underside offers incredible grip to virtually any floor. Each tile has 2 edges with loops, and 2 edges with tabs. They quickly attach to each other by laying the tab of one tile over the loop of the next, and snapping them down into place. The 1-1/2 in. x 12 in. Tiles in gray must be ordered in quantities of 10.
