Abstract
A hold open arm assembly for a door closer to facilitate access to the holding feature by a resiliently biased plunger on a closer arm that is mounted to a soffit plate. A soffit ramp may extend from the soffit plate to provide a sloped surface for engagement by the plunger, leading to the plunger being gradually depressed as the door continues to open and receiving in a recessed area of its free end a rivet head at the soffit plate to hold the door open. When the first arm member pivots relative to the soffit plate and the plunger approaches the head, the plunger engages the sloped surface of the soffit ramp, slides along the sloped surface toward the head, and receives at least a portion of the head in the opening in the free end.
