This Rubber Utility Mat from Little Giant has a non-porous surface that won't harbor bacteria, making it perfect for use in environments with animals. The bottom side is grooved for drainage, and the top side is ribbed for traction. Constructed out of 70% recycled rubber and 30% styrene butadiene rubber (SBR), it won't shrink, curl, or crumble, making it a great option for stalls, trailers, coops, kennels and runs, milkhouses, mudrooms, and more. | Little Giant Pre-Cut Rubber Utility Mat in Black | Size 72"L x 48"W
