## Abstract

A convertible hinge preparation assembly is mounted in hinge cut-outs of a steel door frame or door. The convertible hinge preparation assembly is capable of mounting either regular weight hinges or heavy weight hinges. A plurality of pips are provided for positioning a regular weight hinge. The pips are removed by grinding or drilling when it is desired to mount a heavy weight hinge. In standard weight hinge applications, selective pips, or portions thereof, may also be removed to provide additional adjustment of the installed door and frame assembly to achieve desired operating clearances. The pips are formed by punching the hinge reinforcing member.
