Use template to mark holes on door
Place template on EXTERIOR side of door. Fold template along fold line and place fold line along edge of door, with centerline 5-1/2" (140 mm) above centerline of knob or lever.
Mark hole on face of door. Select desired backset before marking hole. If there is another hole in door, or if you are drilling double doors, make sure to keep the backset consistent.
