2.2 Drill Holes
(1) Paste the provided cutout template on the door as shown in the figure. Mark
1” holes at center of door edge and make 2” holes at the surface of the door (the
offset is 2 3/8” or 2 3/4” from door edge to the center of the 2” hole).
(2) Drill two 1” holes on door edge. And drill two 2” holes on the door surface.
Hint:
To avoid cracking the door surface, the 2” holes should be drilled from
both sides.
(3) There are adjustable backsets for the latch and deadbolt. Set them to either 2
3/8” or 2 3/4” as appropriate for your door.
2.3 Adjust Latch’s Backset
The backset is at the 2 3/8”
position, when the product
is shipped from the factory.
