Door stops are also known as a door stoppers or door wedges. Door stops are used to hold doors open or to prevent damage to doors and walls. Using a door stop can prevent wear or damage to plaster on the walls, saving the need for repairs. Floor mounted door stops are installed onto the floor and are more discrete. They enable you to stop a door from opening into an area or into another object. Floor door stops can be used where there is not a wall or skirting board to attach to. Spring door stops are primary made from a metal spring with a rubber stopper on the end. The spring absorbs some of the force of the door as it hits the door stop. Doorstops can be attached to either the wall or skirting board behind the door, or to the floor where you wish the door to stop. They are attached using fixings such as screws. Door stops that are attached to the wall are usually a few inches above the ground. The rubber dome or cylinder type door stops are sometimes known as a wall bumper.
