ABSTRACT:
A pilot hole hinge and brad door installing apparatus is disclosed which facilitates door installation by the amateur or unskilled craftperson. Hinge plates used for installing doors in accordance with the invention include pilot holes which receive pilot brads to temporarily install a door in its opening after the companion plates of the hinge are permanently installed on either the door or door jamb. While so temporarily installed, a "trial before error" fitting of the door in its opening and accurate location of the companion plates of the hinge for permanent installation of the door is achieved. The door and hinge plate mortise and screw holes are accurately located and the probability of misalignment or destructive error is reduced.
