The Wanderer Folding Plastic Wheel Chocks are designed keep your caravan, RV or trailer stationary when parked. These wheel chocks may also be used in conjunction with Leveller Ramps to provide an extra safety mechanism in the unlikely event that your tyres roll off the leveller ramps. They are suitable for a variety of tyre sizes and are easy to set up. Simply place the two Folding Plastic Wheel Chocks squarely against the centre of the two tyres. The convenience of the folding design when storing the two chocks makes them stand out from comparable products.
