No, it’s not a lock nor a door knob. A door closer is actually an add-on door mechanism that not only closes the door once you open it, but also hampers it to prevent it from slamming too hard. There are two kinds of door closers: the automatic ones and the manually-operated. Manual door closers come in two main forms- the overhead and jamb mounted. The Overhead door closer can be concealed or surface mounted. Meanwhile, the jamb mounted door closer fits between the door and the door frame, and is concealed when the door is closed. Putting one in your door would be necessary to ensure that when you come in your house or go out your room, you won’t have to take a second glance if your door is closed when you go in or leave.
