Abstract: The invention relates to hinge preparation assembly for mounting in each of the mortises formed in the hinge jamb of a steel frame. The hinge preparation assembly includes a hinge reinforcement member having a plurality of spaced apart threaded openings for mounting a leaf of a standard weight hinge set thereto. A hinge conversion means is removably mounted to the hinge reinforcement member so that upon its removal, the hinge preparation assembly is converted from a standard weight hinge preparation to a heavy weight hinge preparation and capable of mounting a leaf of a heavy weight hinge set thereto without requiring changing the hinge jamb of a steel door frame or modifying the hinge mortises thereof.
