This garage threshold seal is crafted from flexible EPDM rubber, built to withstand extreme temperatures and daily vehicle rolling without cracking, shifting or shattering when properly installed, and works on concrete, asphalt, painted or treated surfaces. It blocks water, leaves, dust, dirt, wind-driven rain, grass and snow from entering your garage, reducing condensation-related rust and making the space cleaner, drier and quieter while improving the overall look of your garage door. It also forms a tight seal between the garage door bottom and floor to keep interiors cool in summer and warm in winter, cutting down on heating and air conditioning costs for energy savings. The kit includes two 10 fl. oz. black adhesives, and the 20 ft. long, 3.5-in. wide, 1/2-in. tall strip can be cut to fit your specific garage door size with a sharp knife or aviation shears. It features a bright yellow safety strip for high visibility, anti-slip ridges to prevent slips, and a serrated base for better adhesion.
