Spring fingers normally hold the latch plate against the backing plate in unlatched position. A latch-setting cord extends from the backing plate to a location remote from the door-closer latch mechanism that can be pulled to shift the backing plate toward the door-closer cylinder for canting the latch plate relative to the door-closer piston rod into latched position.
