Door Stops and Holders Information
Door stops and holders are accessories for swinging-style doors that prevent undesired movement of the door.
Door stops may prevent a door from opening too far, when or keep a door ajar when it otherwise would close on its own. Door holders only refer to tools that prevent doors from closing.
There are two factors to consider when selecting a door stop: the distance between the floor and the bottom of the door and the flooring material. The distance between the floor and the bottom of the door is important to ensure that the stop selected is high enough to stop the door and not cause damage. The material of floor is important when choosing a floor mounted design so the stopper does not damage the floor during installation or through use.
There are several designs available for door stops. Some types have the capability of holding the door open at any given point while others are rigidly mounted and mechanically stop the door at a predetermined location.
Baseboard style stops mount to the base board of the wall behind the door. The design can include a rubber tip and spring body to adsorb the force of the door and prevent the stopper from causing wall damage. They are built long enough to prevent the door handle from hitting the wall. This design can come with a hook mechanism to hold the door open but these can often get in the way and are not convenient to use.
Floor mount stops have several styles available. Dome stops are the most common and come in a variety of heights to accommodate residential as well as commercial and ADA regulated doors. Manual stops are taller and may come with a hook to hold the door open. The number of countersuck screw holes on the base of the stopper indicates what type of flooring it can be used on. One countersuck hole is used for mounting to a stud that threads into an expansion shield for concrete floor installation while a three hole design is mounted with three screws to a wood floor.
Wall mounted stops are very popular. There are two factors to consider when selecting a wall mounted stop; these include the distance between the wall and the door when the door is opened to its fullest extent and the wall material. The concave door stop style is designed to come in to contact with a cylindrical lock that has a button on the inside handle that locks and unlocks the outside handle. The depression ensures that the door does not lock when it hits the stopper. A convex option is available for handles without the locking mechanism.
Hinge pin mounts are installed over the hinge of the door. They are out of the way and allow the door to swing open about 100 degrees. They work best for lighter doors.

Door holders simply hold the door open and do not protect the wall or the floor.
Kickdown and plunger type door holders are common designs. They have rubber ends and tend to leave marks on the floor they are dragged by the user.
Magnetic stops and holders engage and hold the door when it is opened to a sufficient degree or when the magnetic stopper is realigned with the holder on the door (as the case with fire doors). The user pulls on the door to free it for closure or when the magnetic is turned off for safety reasons.
Overhead stops and holders are used when the floor or wall cannot be fitted with a stop or holder. When selecting an overhead stop consider other hardware on the door that might be in the way such as a door closer, or vertical rod exit device as well as the width and type of door. For interior applications the overhead stop should be applied to the side of the door opposite the closer to avoid conflict. There are several styles of overhead stops and holders including concealed and surface mounted. They come in a variety of models to fit different applications.
These products are available in various materials and finishes. The material should be selected based on the material of the floor or wall as well as the durability required in the application. A wide variety of finishes are available for aestethics and style.
