What Is a Door Closer?

A door closer is a hydraulic device that shuts a door after being opened, as well as helping to prevent draughts. They are commonly used in schools, commercial buildings, and residential complexes. While they often go unnoticed, a properly working door closer can help prevent injuries caused by slamming doors and keep out unwanted people. However, door closers need to be correctly installed and regularly maintained for their purpose.
