Types
There are four styles of interior door-closer:
- Surface-mounted
- Concealed in frame
- Concealed in floor
- Concealed in door
Surface-mounted door closers come in four variations: slide-track arm, regular arm surface mounted, parallel arm surface mounted, and top jamb mounted. Overhead door closers are typically surface mounted, though most manufacturers offer concealed models too. Such closers mount inside a pocket in the door frame or are mounted in the floor directly under the pivot point and are completely concealed.
Another type of door closer, a surface mounted one, is attached to the door frame behind the door (where the hinges are) next to the middle hinge. The "arm" rests against the door, and a spring that is bent by the user opening the door closes the door by retracting to its proper shape.
There is also the storm door and screen door variation of the door closer: As the name implies, these piston shaped closers are used on storm, security, and screen doors which give the home an extra line of defense against weather, intruders, and insects. Whereas interior closers typically use hydraulics, storm door closers are more typically pneumatic, using air and springs to close the door. Storm Door closers generally have a small metal washer on the rod that is used to lock the closer in the open position when moving stuff in or out, but more recent models such as the Touch 'n Hold door closer have a button to actuate the hold open feature to make this process easier.
Finally, there is the concealed, jamb-mounted door closer, which fits in morticed recesses in the door and door frame and is totally concealed when the door is closed. These are available in controlled and uncontrolled versions, selected according to the application for which they are intended.

Famous quotes containing the word types:
“The wider the range of possibilities we offer children, the more intense will be their motivations and the richer their experiences. We must widen the range of topics and goals, the types of situations we offer and their degree of structure, the kinds and combinations of resources and materials, and the possible interactions with things, peers, and adults.”
—Loris Malaguzzi (1920–1994)
“He types his laboured column—weary drudge!
Senile fudge and solemn:
Spare, editor, to condemn
These dry leaves of his autumn.”
—Robertson Davies (b. 1913)
“As for types like my own, obscurely motivated by the conviction that our existence was worthless if we didn’t make a turning point of it, we were assigned to the humanities, to poetry, philosophy, painting—the nursery games of humankind, which had to be left behind when the age of science began. The humanities would be called upon to choose a wallpaper for the crypt, as the end drew near.”
—Saul Bellow (b. 1915)
