ABSTRACT:
A blocking device for preventing a door closer from achieving a degree of rotation corresponding to a door hold-open position. A blocking device is provided which can be selectively protruded into a door closer housing to block the translation of a cam plate under influence of a rotating cam operatively connected to one of either the door or the door frame such that the 90.degree. or 105.degree. typical door hold open position cannot be achieved. The blocking device can be a rotatable limit bar which can be positioned to an interference or no-interference position, or it can be screw pins which can be threadingly inserted into the housing to block either the cam or other moving portions of the door closer such that the closer cannot achieve the door hold open position.
