The Guardian 3-Foot Long Heavy-duty Rubber Parking Curb is designed to help define parking spots and to prevent cars from damaging walls, landscaping, sidewalks or other cars. The highly visible parking stop is resistant to extreme temperatures, UV light, oil, gas, and moisture, so it can be used indoors or outdoors without worry. A flexible rubber construction conforms to uneven surfaces and the stop can be used temporarily or permanently on concrete or asphalt surfaces. This rubber car stop won't chip, crack, crumble, or corrode like concrete curbs.
