Oct-O-Flex™ is a heavy duty outdoor entrance mat made with tough SBR rubber to remain flexible and withstand extreme cold and the harshest of weather conditions. The unique design has holes to drain water and debris away from the entrance, while the smooth top surface and beveled edges on all four sides make it wheelchair and cart friendly. A raised knobbed underside combined with the weight of the mat helps to eliminate mat movement. Oct-O-Flex™ is the perfect choice for outside high traffic areas. FOB Shipping Point.
