Abstract: An electrically releasable hold-open device for use with a door closing mechanism employing a latch device that is engaged by an element reciprocating in a trackway. The element when moved to hold-open position shifts the latch device up an inclined ramp to a location in which the latch device is releasably held by retaining means. The retaining means is controlled by an electrically energized solenoid so that it is released in the event of an emergency.
