Abstract

An apparatus for reinforcing a door frame, comprising a pair of elongated metal plates extending substantially the length and width of the jambs forming either side of the door frame. Each of the metal plates defines a plurality of attachment holes for attaching the plates individually to the back sides of each of the jambs with fasteners passing therethrough. In addition, each plate defines a plurality of installation holes for allowing the door frame to be secured in the framed opening with fasteners passing through the jambs, the installation holes, and into adjacent members of the framed opening. Each plate further defines a plurality of openings along the lengths thereof, which allows attachment of appropriate hinges or strike plate to the front side of the corresponding jamb by fasteners passing through the hinge or strike plate, the jamb, the openings, and into an adjacent member of the framed opening.
