Hold-Open Device

Some door closers have a 'hold-open' feature which allows the door to be fixed in an open position at a set angle until the door is pushed/pulled past that angle, at which time the door will close. This feature is only suitable for use on a fire door is the hold-open is electro-hydraulic as these models will release the door in the event of a fire or power cut.
