If you have confirmed that the existing holes are compatible with your new lock, please proceed to step 2 (skip step 1c).
If you need to make adjustments, go to
step 1c and find the closest match to each
aspect of your door on the Marking Template.
Tear off the Door Checker (pages 56) and follow the guidelines on both sides to
measure each aspect of your door and frame. There are some cases when existing
holes cannot be adjusted to be compatible.
Please do not drill any holes until you confirm that your door is compatible.

1c Make or Adjust Holes
Skip this step if you have confirmed that the existing holes are compatible (step 1b).
1. Tear off the Marking Template (pages 78), and choose the
preferred face bore diameter (2- 1/8” or 11/2”) on either side
of the template.
2. Tape the Marking Template onto the door as shown.
3. Check the door thickness. It should match either the shape
with solid outlines (13/4”), or the one with dashed outlines
(13/8”).
3a. Use solid lines as a template for 13/4” door thickness.
3b. Use dashed lines for 13/8” door thickness.
4. Choose your preferred backset. It should match either the
shape with solid outlines (23/4”), or the one with dashed
outlines (23/8”).
4a. Use solid lines as a template for 23/4” backset.
4b. Use dashed lines for 23/8” backset.
5. Drill holes in your door where marked.
6. On the door frame, align the center of the strike plate with the
center of the edge bore. Trace the strike plate, then chisel to the
depth of the strike plate so it sits flush with your door frame. Drill
the 1” diameter strike pocket with a minimum depth of 1”.
