1. Determine the Position of Backset
    • “Backset” refers to the distance between the door edge and the center of the bore hole for the deadbolt. The adjustable latch fits both backset of 2-3/8" (60 mm) and 2-3/4" (70 mm).
  2. Use the Paper Template to Mark Drilling Spots
    • Select the height and backset as desired on the door face; use the attached TEMPLATE as an indication to mark the center of the circle on the door and the center of the door edge.
  3. Drill Holes
    • Use the marks as a guide to drill a hole Ø2-1/8" (54 mm) through the door face for the lockset, then a hole of Ø1" (25.4 mm) for latch.
  4. Chisel out a Groove for the Latch
    1. Insert the latch and ensure it is parallel to the door face. Mark the outline of the faceplate, then take out the latch.
    2. Chisel 5/32" (4 mm) deep along the outline to allow the faceplate to be aligned with the door edge.
  5. Drill a Hole for the Strike Plate
    1. To identify the center of strike: close the door to lay the latchbolt against the door frame. Mark the center line on the doorframe exactly opposite the latch hole in the door edge.
    2. Measure one half of door thickness from door stop and vertically mark centre line of strike.  Drill 1" (25.4 mm) hole, 1" (25.4 mm) deep at intersection of horizontal and vertical line of strike.  Chisel 5/64" (2 mm) deep along the strike outline to allow the strike to be aligned with the doorframe.
