A door closer is a mechanical device that automatically closes a door after it has been opened. Door closers are typically used on exterior doors, but they can also be used on interior doors in high-traffic areas. Adjusting a door closer is a relatively simple task that can be completed with a few basic tools.
There are many benefits to adjusting a door closer properly. A properly adjusted door closer will help to keep the door closed, which can help to improve security and energy efficiency. It can also help to reduce noise and wear and tear on the door and frame.
