Abstract: A lockable door hardware assembly for securing a door in closed configuration includes a mortice lock that is coupled to a door. The mortice lock comprises a latch bolt, which in turn comprises a head and a shaft. The head is circumferentially larger than the shaft. A strike plate is mounted to a doorframe in which the door is positioned. A channel extends into the door from an interior surface of the door so that the head of the latch bolt is positioned between the doorframe and the channel when the latch bolt is extended through the strike plate. A rod is selectively insertable into the channel. The rod is positioned to abut the head of the latch bolt to prevent the latch bolt from retracting from the strike plate, thereby rendering the door unlockable from either side of the door.
