Door closers close fire doors behind a person passing through the door and therefore
help limit the spread of
fire throughout a building. Overhead door closers can be mounted in three different
configurations which are commonly referred to as Fig 1, 61 and 66 positions (please note that not all closers can be mounted in all configurations)
Door closers come either with a rated or
adjustable strength to cater for different sizes and weights of doors. View our
