摘要： A security door system includes a door frame, a door, and an astragal. The door frame has first and second vertically extending side members that define an opening therebetween. The door is disposed within the opening and is secured to the frame via a hinged connection along the first vertically extending side member. A gap is defined between an edge of the door, that is opposite the hinged connection, and the second vertically extending side member when the door is in a closed position. The astragal has first and second plates that are secured to an outer surface of the door. The first plate extends beyond the edge such that the first plate covers the gap when the door is in the closed position. The second plate extends from the first plate in a direction away from the edge and toward the hinged connection.
