Blue color is ideal for use to identify handicap accessible parking spots. Rubber Car Parking Stops help drivers stop their cars before hitting your curb, parking garage wall, or other areas you want to protect. While concrete and plastic parking stops crack and chip over time, looking unsightly, this rubber parking stop will not warp, chip, or crack. Tough, recycled tire rubber is resistant to weather, salt, moisture, UV rays, oil, and extreme temperatures. Embedded high visibility striping made of white road marking tape makes parking blocks more visible at night. The parking stops have pre-drilled holes and are portable, making them a quick, one-person installation. Material: Recycled Materials.
