Door Closer Types

Door closers mainly include exterior-mounted and interior-mounted types, specifically top-mounted door closers, bottom-mounted door closers (also known as floor springs), vertical door closers, and concealed hinge door closers.

Top-mounted door closers: This is the most common type, typically installed at the door header. These spring-like hydraulic devices compress and then release when the door is opened, automatically closing it.

Bottom-mounted door closers (floor springs): These are installed at the bottom of the door and use hydraulic pressure to automatically close the door.

Vertical door closers: These are installed in the middle of the door and also use hydraulic pressure.

Concealed hinge door closers: These are interior-mounted door closers, often installed inside the hinge for greater concealment.

Door closers can also be categorized by function into two types: fixed-position door closers and non-fixed-position door closers. Fixed-position door closers allow the door to stop after opening to a certain angle, while non-fixed-position door closers automatically close after reaching the maximum opening angle.
