Heavy, 100% static dissipative nylon face offers outstanding absorption and durability. Tight, heat-set, Ultra-Twist™ yarn construction resists packing and crushing. Dirt filters into the mat face rather than remaining on the top. Molded rubber backing resists curling and cracking in all types of weather. Available in flat, gripper and suction backing types. Also available with oil and grease resistant 100% nitrile rubber backing when applications call for additional protection.
