Abstract
A hinge-like device for securing the hinge side of a door against "kick-ins." The device comprises a jamb leaf that extends outside the area protected by a closed door so that a buck pin projecting through the extended portion can engage the strongest part of the wall structure. A cover plate is provided to prevent access to and removal of the buck pin, and the cover plate is itself irremovable because its mounting screws are shielded by a closed door. A door leaf secured to the inner surface of the door is loosely fitted to the jamb leaf.
