Corners create a finished look and a safer edge for ergonomic matting, and they're sold individually so you can order the number you need without waste and without trimming components to fit. The ramp edge allows you to roll carts and dollies easily on and off a mat, and positive interlocking connections keep it firmly attached, so you can move a row of matting quickly for easy floor maintenance. Made from a nitrile rubber compound, this part resists petroleum-based fluids.
