Wheel StopsThese wheel stops secure parked vehicles and trailers from rolling away. These wheel stops are made of UV resistant plastic and suitable for use with wheel loads of up to 6500 kg. As the wheel chock is made from plastic, it is much lighter than comparable metal chocks. Comes in 2 colours, Black and Yellow which makes it easier in the dark due to the yellow warning colour. Please select which colour your would like before checking out.
