Fire door closers close fire doors behind a person passing through the door and therefore help limit the spread of fire throughout a building. Overhead fire 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)
Fire door closers come either with a rated or adjustable strength to cater for different sizes and weights of doors. View our EN size guide
