Abstract
Closer arm assembly includes a main arm having a first end fixed to the output shaft of a closer fixed to one of a door and a door jamb so that the main arm pivots when the output shaft rotates, and a connecting arm having a first end pivotably connected to the main arm and a second end connected to the other of the door and the door jamb. The connecting arm contacts a stop to limit relative pivoting of the arms, the stop including a cushion with a contact surface which suppresses noise as the connecting arm contacts the cushion. The stop can be in the form of a spring loaded bumper fixed to a soffit plate, or a pin fixed to the second end of the main arm. A hold open device can be fixed to the connecting arm for engaging a feature on either the soffit plate or the main arm, the hold open device having a spring loaded detent which is released by manually turning a knob.
