4. Install Latch
a. Insert the latch and lay the faceplate against the door
edge.
Use a pencil to mark it's perimeter, then take out the
latch.
b. Chisel out the portion you've marked with pencil to
about 4mm (5/32") deep. Score the area within the
borders as clearly and precisely as possible.
Ensure the plate can fit flush with the door edge surface.
d. It is not necessary to chisel the door edge for the
faceplate installation if you use a drive-in latch. (not incld)
You may install it into the edge bore directly, making
sure the bevel faces the outside assembly.

Be sure the holes for thru-bolts (next to the adjustable
