ABSTRACT:
The removable mullion assembly allows a mullion to be removed, thereby allowing wider objects to pass through double doors. The top fitting of the assembly includes a spring loaded retaining bolt which locks the mullion in place. A locking mechanism attached to the top fitting allows the retaining bolt to be disengaged from the mullion. However, in the event of a fire, a meltable platform within the top fitting releases a deadlock, which mechanically blocks the retaining bolt from disengaging the mullion.
