  • Door hinge template for use with a router
    Patent number: 5042543
    Abstract: A door hinge template that is used with a router to form the recess in a door jamb and also a recess in the edge of a door so that a door hinge can be installed. The door hinge template has been designed to be used with 13/8 inch doors and 13/4 inch doors. The template has integrally formed captive nail assemblies for mounting the template to either a door jamb or the edge of a door. Two sets of alignment windows in the bottom wall of the template allow it to be either visually aligned or allow the alignment to be felt by handtouch. Removable spacer members allow the rectangularly shaped aperture in the central portion of the template to be adjusted so that it can be used for routing a recess for either 31/2 inch hinges or 4 inch hinges.
