What is a concealed door closer?

Concealed fire door closers provide the functionality of an overhead door closer but are fitted within the door leaf and frame. 

This type of installation is aesthetically pleasing and helps to reduce vandalism, as most of the door closer is hidden from sight.

A door closer is defined as any mechanical device that closes a door in a controlled manner, preventing it from slamming, in general after someone opens it, or after it was automatically opened. 

The most common examples can usually be found in schools, convenience stores, and a multitude of other smaller businesses and public buildings.
