What Is A Hollow Metal Door Closer
A hollow metal door closer is a mechanical hydraulic device used to automatically close a hollow metal steel door behind a pedestrian once they have used the door. Hollow metal door closers are often more heavy duty than normal door closers due to the fact that hollow metal doors are heavy doors constructed from 18 gauge steel.

Types Of Hollow Metal Door Closers
Surface Hollow Metal Door Closers
Hollow metal door closers are typically surface mounted door closers. They are designed to mount either to the steel door or the hollow metal frame. Higher quality hollow metal door closers will come tri-packed allowing the door closer to mount in any of the 3 configurations:

Top Jamb (Push Side): Door closer body is mounted to the top of the hollow metal frame head on the push side and the the door closer arm is mounted to the top of the steel door.

Regular (Pull Side): Door closer body is mounted to the top of the hollow metal door on the pull side and the door closer arm is mounted to the hollow metal frame head.

Parallel (Push Side):


Concealed Hollow Metal Door Closers
Concealed hollow metal door closers are designed to mount within the door frame, unseen by the pedestrian eye. Concealed hollow metal door closers are actually rarely seen due to the extensive prep work of the door and frame, but they do exist.
