ABSTRACT:
A reinforcing structure for an associated door and lock mechanism of a type having a bolt. The door abuts an elongated door stop carried on a door jamb in the closed position. A strike plate has a bolt receiving aperture therein and is dimensioned and configured to have at least portions extending into recesses in the associated elongated door stop. Screws extend through the portions for mounting the strike plate on the associated door jamb. A jamb plate is dimensioned and configured for mounting on the door stop with a first edge thereof in generally parallel relationship to a side of the strike plate and extending substantially to an edge of the door stop which abuts the associated door when in the closed position. In some forms of the invention a first reinforcement plate is disposed on at least one side of the door, surrounding means for operating the bolt, and is dimensioned and configured for extending into the recess in the jamb plate.
