Abstract

See full text

A door security device has a rail support including a top surface and a bottom surface. A door support is attached to the rail support, such that the door support extends vertically away from the rail support of the door security device. The door support is oriented at a normal relative to the rail support. The bottom surface of the rail support rests parallel to a surface of a rail of a crash bar when the bottom surface is situated adjacent the surface of the rail. The security device creates a rigid connection to prevent unwanted removal of the door from a closed position.
