Products with a free-swing mode will allow for the door to be swung to any position up to a certain maximum angle, and will remain in this position whilst the unit is latched open. The door will still close in the event of a fire. A free-swing door closer makes the door feel light and easy to move.
This mode is suitable for locations where there is not a need for the door to be rigidly held open. Building regulations recommend free-swing door closers for bedroom doors.
