An overhead mounted door holder assembly for attachment between a door jamb and a door, to hold the door in an open position, includes a jamb bracket attached to the door jamb and a jamb arm pivotally attached to the jamb bracket. A channel assembly having a longitudinally extending channel is attached to the door, and first and second end caps are attachable to opposing ends of the channel assembly, with each end cap being held by a retaining key in locked connection with the channel assembly. The first and second end caps are configured to allow alternate positioning of the channel assembly inset in a top of the door or attached to a side of the door. A hold open stop is fixably held in the channel of the channel assembly. The hold open stop is configured to have a stop element for engaging a slide assembly pivotally attached to the jamb arm and positioned for longitudinal movement in the channel. The slide assembly is configured to engage the stop element of the hold open stop and hold the door in an open position. The force required to engage the hold open stop and the slide assembly is determined by the position of an adjustment wedge.
