Abstract: A door template for use in cutting a door to fit in a door jamb. The template has inner and outer upright members. A horizontal top rail is secured to the upper ends of the upright members in vertically adjusted position. A horizontal bottom rail is secured to the lower ends of the upright members in vertically adjusted position. Each rail has an outwardly extending horizontal extension bar. The inner upright member has a vertical inner edge. The top rail has a horizontal top edge. The bottom rail has a horizontal bottom edge. The template, after suitable adjustment, is adapted to be laid over a door blank and the proper door size transferred to the door blank by running a marker or the like along the inner edge of the inner upright member, the top and bottom edges of the top and bottom rails, and a straight edge connecting the outer ends of the top and bottom extension bars. The template also includes a drill plate with holes for guiding a drill to form holes in the door for hardware.
