ABSTRACT:
The improved guard plate of this invention is used to protect the cylinder of a lock. It includes a relatively flat body, attached to the door in the vicinity of the cylinder, and a disc rotatably mounted between the door and the flat body. In an open position, an opening in the disc permits access to the cylinder; and, in the closed position, the solid portions of the disc do not permit access to the cylinder. In addition, rotatable fingers are provided so as to lock the rotatable discs in either the open or closed position.
