The Alexander and Wilks portable free-standing door stops are satin chrome and are available in three sizes. As these door stops are portable they can be placed wherever you wish to hold the door open or prevent it from banging into a wall. With a rubber ring around the circumference to cushion the door and a rubber base to help stop it from slipping. Particularly useful for tiled floors, underfloor heating situations, and other areas where fixing would be difficult.
