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. ## Claims ### Claim 1 A security door system comprising: a door frame having first and second vertically extending side members that define an opening therebetween; a door disposed within the opening, secured to the frame via a hinged connection along the first vertically extending side member, wherein 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; and an astragal having first and second plates that are secured to an outer surface of the door, the first plate extending beyond the edge such that the first plate covers the gap when the door is in the closed position, the second plate extending from the first plate in a direction away from the edge and toward the hinged connection. ### Claim 2 (depends on 1) The security door system of claim 1, wherein the first plate extends vertically between a top and a bottom of the door. ### Claim 3 (depends on 1) The security door system of claim 1, wherein the second plate extends horizontally in a direction away from the edge and toward the hinged connection. ### Claim 4 (depends on 1) The security of door system of claim 1, wherein the second plate spans between 25% and 75% of a distance between the first plate and the hinged connection. ### Claim 5 (depends on 1) The security door system of claim 1, wherein the door further comprises a door handle, and wherein the door handle is secured to an opposing side of the door relative to the astragal. ### Claim 6 (depends on 1) The security door system of claim 1, wherein the first and second plates are coplanar. ### Claim 7 (depends on 1) The security door system of claim 1, wherein the first plate has a height to width ratio that ranges between 5:1 and 15:1. ### Claim 8 (depends on 1) The security door system of claim 1, wherein second plate has a height to width ratio that ranges between 1:4 and 1:1. ### Claim 9 A security astragal for a door comprising: a vertically extending plate that is configured to cover a gap defined between an edge of the door, that is opposite a hinge, and a door frame when the door is in the closed position; and a horizontally extending plate protruding from the vertically extending plate in a direction away from the edge and toward the hinge. ### Claim 10 (depends on 9) The security astragal of claim 9, the vertically extending plate and horizontally extending plate are coplanar. ### Claim 11 (depends on 9) The security astragal of claim 9, wherein the vertically extending plate has a height to width ratio that ranges between 5:1 and 15:1. ### Claim 12 (depends on 9) The security astragal of claim 9, wherein horizontally extending plate has a height to width ratio that ranges between 1:4 and 1:1. ### Claim 13 (depends on 9) The security astragal of claim 9, wherein a ratio of a height of the vertically extending plate relative to a width of the horizontally extending plate ranges between 3:1 and 5:1 ### Claim 14 A security door system comprising: a door frame defining an opening; a door disposed within the opening, secured to the frame via a hinged connection along a first edge of the door, wherein a gap is defined between a second edge of the door, that is opposite the first edge, and the door frame when the door is in a closed position; and an astragal secured to an outside surface of the door between the first and second edges, the astragal having a vertically extending plate and a horizontally extending plate, wherein the vertically extending plate extends beyond the second edge and covers the gap when the door is in the closed position, and wherein the horizontally extending plate extends from the vertically extending plate in a direction away from the second edge and toward the first edge. ### Claim 15 (depends on 14) The security door system of claim 14, wherein the vertically extending plate extends between a top and a bottom of the door. ### Claim 16 (depends on 14) The security of door system of claim 14, wherein the horizontally extending plate spans between 25% and 75% of a distance between the first plate and the first edge. ### Claim 17 (depends on 14) The security door system of claim 14, wherein the vertically extending plate and horizontally extending plate are coplanar. ### Claim 18 (depends on 14) The security door system of claim 14, wherein the vertically extending plate has a height to width ratio that ranges between 5:1 and 15:1. ### Claim 19 (depends on 14) The security door system of claim 14, wherein horizontally extending plate has a height to width ratio that ranges between 1:4 and 1:1. ### Claim 20 (depends on 14) The security door system of claim 14, wherein the door further comprises a door handle, and wherein the door handle is secured to an opposing side of the door relative to the astragal.
