Abstract
A self-latching flush bolt for use in the inactive door of a pair of swinging doors, the bolt being on a slide rod which is spring actuated to throw the bolt into engagement with the strike when the trigger is contacted by the active door. A dead-locking lever holds the bolt locked as long as the trigger is depressed; when the active door is opened the bolt may be manually retracted and will be held in retracted position until the trigger is activated. A roller on the bottom bolt rolls on the floor in case the bolt is thrown with the door in an open position.
