Rubber-Cal''s Wide Rib Corrugated Rubber is a 3mm thick virgin rolled rubber mat and runner that is available in either a 36 inch or a 48 inch width that offers excellent traction with wider grooves and protrusions. The surface pattern (which is comprised of wide ridges and valleys) is more prone to trapping and cleaning debris and liquids from heavy foot traffic while maximizing the ease of cleaning and comfort. Wide Rib Corrugated Rubber is designed for light to medium foot traffic where traction and increased safety is needed and performs especially well in transient or temporary applications (e.g. wet aisle ways, catered parties, temporary walkways, etc...). The fabric base-finish adds subsurface traction, keeping the runners bottom surface secure to the floor. Since this product is made from virgin SBR and it creates a completely watertight surface, offers moderate chemical resistance, and can be cleaned with most common household cleaners. Strong, highly caustic cleaning solutions (e.g. bleach) are not recommended. The lengthwise running corrugations inherently direct foot traffic as well as maintain a level of safety that is unmatchable by other runner products.
