Door closers can come in handy. They close the door behind you and can be adjusted to keep the door open when, for example, you are bringing in the groceries from the car, or large items of furniture into the house.

What is a door closer?

It’s a mechanical device that can close the door in a controlled fashion. There are basically two types; hydraulic or liquid closers, and pneumatic or air closers. Both of these perform the same function. There are also lightweight or heavy-duty door closers designed to match the weight or purpose of the door.
