  • Outfit a rotary tool with a 650 router bit and 335 plunge router attachment.
  • Set the depth of cut on the router attachment to match the thickness of the faceplate.
  • Test cutting depth on a scrap of wood. The depth of the cut should allow the faceplate to align flush with the edge of the door.
