ABSTRACT:
A 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 a hold open stop is fixed in the channel of the channel assembly. The hold open stop is configured to have a stop element with a first ramp and a second ramp engageable by a slide assembly. The slide assembly is pivotally attached to the jamb arm and positioned for longitudinal movement in the channel, with the slide assembly having a slide frame configured to support a rocker pivotably connected to the slide frame. The rocker has a catch on one side of a pivot and rocker face on the opposite side of the pivot, with the catch configured to slide over the first ramp for reversible engagement with the second ramp of the stop element to hold the door in an open position. The force required to slide the catch over the first and second ramps is determined by the preload force on an adjustment wedge that engages the rocker face.
