ABSTRACT:
Disclosed is a security astragal that is secure against unauthorized removal but can be easily removed when authorized so that the door can be subsequently reused without the astragal. The disclosed security astragal includes a security bar that protects against tampering with the door latching mechanism and a protective sheath that secures the security bar from unauthorized removal.
