ABSTRACT:
The invention relates to hinge preparation assembly for mounting in each of the hinge mortises formed in the hinge edge of a steel door. The hinge preparation assembly includes a hinge reinforcement member having a plurality of spaced apart openings including threaded openings for mounting a leaf of a standard weight hinge set thereto. A hinge conversion member 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, which is capable of mounting a leaf of a heavy weight hinge set thereto without requiring changing the door, modifying the hinge mortises thereof or the hinge preparation assembly.
