Is your wall getting damaged because it is repeatedly hit by the knob when you open the door? Then you need to install a door stop. Do you need to keep your door open in certain situations? A door stop can also solve this problem.
Door stops control the opening of a door to a certain point. They can also stop a door from closing when you need it to remain open for a certain period. Serving either or both functions, door stops come in several different types. These include decorative stops, which are often used in homes as stoppers to prevent a door from closing; floor stops, which are installed on the floor to prevent a door from opening too wide and, at the same time, can keep a door open as needed; and wall stops that function similarly to floor stops but may not be advisable in high-traffic areas. There are also overhead stops and door closers.
