Diamond-Plate SpongeCote is now available with a GritWorks! surface. It's ideal for primarily dry areas with slight overspray or where grease and oil get tracked onto the mat. GritWorks! is a carbide grit that increases traction by over 50% while also increasing the chemical resistance and durability of the surface. Available in two thicknesses, a standard 9/16" and an UltraSoft 15/16", Diamond-Plate with Gritworks! has a super resilient, Nitricell sponge base. Nitricell sponge is PVC, loaded with Nitrile rubber for exceptional comfort, rebound and long life. All mats come with safety-beveled edges.
