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.

An improved door bottom and sill assembly for inswing exterior doors is disclosed. The door bottom and sill assembly consists of a bottom portion and a sill portion. The bottom portion has a sealing member along the interior bottom edge of the door. The sill portion mates with the sealing member when the door is in a closed position, forming a tight weather barrier.

Inswing door bottom and sill assembly

An improved security strike plate assembly is provided. The assembly consists of a wrap-around security plate which normally includes an adjustable strike plate. The security plate extends around three sides of a wood lock-side jamb member to which it is mounted in order to enhance the impenetrability of the door by preventing splitting of the lock-side jamb and resultant dislocation of the strike plate and keeper during thrusts against the door. The strike plate is adjustable without removing the security plate to accommodate slight variations in the size or shape of the door or frame during seasonal or atmospheric changes.
