Door closers guide

Door closers increase the loading on hinges and the rate at which they wear. When selecting hinges, please consider the table below for the increase in door weight based on the door closer used and the level of door usage.

  With backcheck* Without backcheck
Light use Add 65% Add 10%
Medium use Add 75% Add 20%
Heavy use Add 90% Add 35%

*A backcheck function on a door closer prevents the door from being opened too far by excessive force or a gust of wind. None of the door closers supplied by Howdens Joinery have this function available.
