ABSTRACT:
This invention provides a method and apparatus for preventing an ordinary door knob from being rotated, thus preventing the plunger-type bolt from disengaging from the striker plate and plunger pocket in the door jamb. The apparatus is attached to the shaft of the door knob on the deepest side of the door jamb. Once secured in place by the locking mechanism, enclosing all but the shaft of said door knob, its shape and design will prevent any effective rotation of the apparatus, or the door knob, due to its proximity to the door jamb nearest the door knob.
