The Durable RPC-366GY heavy-duty plastic parking block is gray and can be used in a parking space to prevent the front wheels of a car from rolling too far forward. Plastic resists weather, wear, and impacts and doesnt need to be painted. The parking stop weighs 35 lb. and measures 6 x 6" x 4" (L x W x H). (L is length, the horizontal distance from left to right; W is width, the horizontal distance from front to back; H is height, the vertical distance from lowest to highest point.)
Wheel chocks (also called wheel immobilizers or chock blocks) are designed to help prevent vehicles from accidentally rolling when parked, especially on a grade. Primarily for the safety of workers when a vehicle is undergoing maintenance, or being loaded or unloaded, use of wheel chocks can also reduce property damage from accidents and loss from spillage during loading operations. Wheel chocks are typically wedge shaped, and the size required depends on the weight of the vehicle, the size of the tires, the steepness of the grade, and the quality of the road surface. Large wheel chocks are usually made of a durable material with a high strength-to-weight ratio, and include handles or ropes to facilitate manual deployment. Occupational Safety and Health Administration (OSHA) and Mine Safety and Health Administration (MSHA), both agencies of the U.S. Department of Labor, require wheel chocks in several specific situations (including when parking on a grade and during loading operations).
