ABSTRACT:
An arm for a door closer includes a shaft rotatable about a first axis. The arm includes a first arm member having a first end connected to the shaft and rotatable therewith. A second arm member has a first end pivotably connected to a second end of the first arm member and a second end pivotably connected to a mounting bracket. The second arm member includes an open ended axially movable housing member having radially inwardly extending detent. A clamp has a first end forming the first end of the second arm and a second and forming radially expandable jaws of the clamp. The detent on the housing when disposed in a first axial position maintains the jaws in a closed position and when moved to a second axial position permits the jaws to radially expand. A link has a first end forming the second end of the second arm and a second end. A joining member is connected to the second end of the link and extends towards the clamp. The joining member is held in a fixed position by the jaws when the jaws are closed and is axially movable relative to the clamp when the jaws are radially expanded.
