A rubber wheel stopper is a device used to prevent vehicles from rolling forward or backward when parked. It is typically made of durable rubber and designed to be placed at the end of a parking space or in front of a wall to provide a physical barrier for the vehicle's tires. Rubber wheel stopper is mainly used in parking lots, garages, and other areas where vehicles need to be parked safely and securely. It can also be used to mark the boundaries of parking spaces, prevent vehicles from hitting walls or other objects, and reduce the risk of accidents or damage to property.
