ABSTRACT:
Method and apparatus for facing wooden door jambs eliminating need for spacers. The apparatus comprises at least one profiled steel jamb facing member having an aperture of a diameter equal to the root diameter of the screw to be screwed therein, thereby preventing the screw from rotating further once the screw head engages the rim of the aperture. The profiled member is first aligned and levelled relative to the door jamb, held in place, and the screw inserted and tightened until it cannot be further rotated. Thus, the plumb and level position of the member is determined in advance and fixed merely by insertion of the screw as far as it can turn.
