Basically there are 2 types of door closers:

  1. Surface mounted door closers
  2. ​Concealed door closers



1. Surface mounted door closers are by far the most common type. They are distinguished predominantly by the way they are mounted and are popular due to ease of installation by the contractor (on site) and are generally chosen due to budget restrictions.


Mounting types:

  • Standard mount - for pull side of door ($)
  • Top jamb (transom or header) mount - for push side of door ($)
  • Parallel arm installation - for push side of door ($$)
  • Slide arm track installation - for push or pull side ($$)
  • Corner mount - Arched or angular doors - very rare

























​Surface mounted closers are obtrusive and aesthetically none of them will win a beauty contest as they exude an institutional look.  They should be used where they are not generally seen such as Fire stairwells or underground car parks. Contractors often persuade architects and owners to settle for an exposed closer because they are easy to install and cost less in materials and labour.  There are certain applications that require an exposed closer, some automatic door options and where a refurbishment or retro-fit project requires a relatively simple installation process.

2. Concealed door closers - The choice of Architects and Interior Designers

They are aesthetically pleasing as they are hidden from view. Each type of concealed door closer has its merits and as such you need to select the concealed closer best suited to your specific type of door and installation.

  • Concealed in floor

Semi-Concealed closers were the first foray into enclosing a door closer in the door leaf and for many years were the most popular hidden closer with architects and designers. Some can be used in fire doors  when installed with the approved intumescent gaskets. They need to be part of the door pre-fabrication process and are not suitable for refurbishment or retro-fitting. The door face needs to be cut away and a large channel morticed into the frame. Can be mounted in frame header. $$$
