Bring rich earth tones to your entry with the NoTrax Opus Indoor/Outdoor Rug - Slate Blue. This rug is made of polypropylene and features molded rubber cleats on the underside to prevent slipping. The raised diamond pattern facilitates scraping while the channels and raised rubber border on all sides retain moisture and debris. At only 0.375 inches thick and with 32 ounces of tufted yarn per square yard, this mat has increased moisture retention and is easier to clean. It is a recommended and approved product as part of the GreenTRAX program for Green Cleaning environments. Available in a variety of sizes, this rug is intended for commercial use.
