An improved astragal for use in a double door assembly having an active door and a relatively inactive door is disclosed. The astragal has a vertically extending mullion housing which is attached to the free edge of the relatively inactive door. A vertically extending slide section is mounted on the mullion housing on the sealing side of the free edge of the inactive door. The slide section extends from the free vertical edge of the inactive door when the active door is in the closed position. The slide section is vertically movable from an unlocked position to a locked position wherein the slide section is moved vertically downward with respect to the mullion housing to engage the sill/threshold of the door frame, thereby preventing any movement of the inactive door.
