Door stops are hardware devices that can serve two functions. They may be used to stop the door from opening past a certain point, or used to stop the door from closing. There are a number of different types of door stops, and many are capable of performing both of these stop-related functions.
Decorative door stops are some of the most widely used stops in residential applications. They are made from iron or ceramic, and formed into decorative shapes or statues. These heavy objects are then placed in front of an open door to hold it open until the stop is moved. This variety is rarely used in commercial settings.
Floor stops are devices installed at floor level to stop a door from opening too wide. They help to protect nearby walls or furnishings from damage caused by the doorknob or the edge of the door itself. These stops generally consist of small metal domes that are screwed into the floor. They may also feature magnets or chain and hook options that allow the device to both stop the door and hold it open as needed. Rubber wedges are also considered a type of floor stop, and are widely used in both commercial applications and homes.
Wall stops are used to stop a door from hitting the wall and causing damaging. They are used when a floor stop is impractical, or when a floor stop might pose a trip hazard. Wall stops are screwed into the wall at the top of bottom of the door, and generally feature a rubber or plastic tip to protect the door. Some may feature a chain and hook option to hold the door open in addition to stopping it. These stops generally don't hold up well in high-traffic applications.
Overhead stops are hardware devices that consist of a metal arm and a low profile case. The body of the stop is installed on the face of the door, and the metal arm connects to the frame. This device can be adjusted to control how widely the door can open. Generally, these stops are set between 90 and 110 degree of maximum opening. Many overhead stops are designed to allow the body of the device to be concealed within the door or frame.
Door closers are hydraulic devices used to automatically close doors after they are opened. They consist of a metal body, which may be installed on either the door or the frame, as well as a steel arm that connects the body to another part of the opening. Most closer models come with optional stop arms, which can be adjusted to stop the door from opening past a certain point. The stop on a closer may be a compression type device, or a simple metal button that blocks the arm from opening past a certain point.
