Thru hole

A. Bore a 2¹⁄₈" (54 mm) hole and two (2) ⁵⁄₁₆" (8 mm) holes

from both sides of door to avoid splintering wood.

B. Bore a 1" (25 mm) hole into door edge. Using the latch faceplate

as a pattern, trace outline and mortise the door edge so the latch
is flush with door. If ³⁄₄" projection latch is to be installed see Step 19.

Note: For wood jambs, close the door and using a strike-locating tool
or other pointed object, mark the position of the hole in the jamb.
Open the door and drill 1" (25 mm) hole in the jamb a minimum of ³⁄₄"
19 mm) deep.

C. File two (2) ⁵⁄₃₂" (4 mm) x ⁵⁄₃₂" (4 mm) x ¹⁄₈" (3 mm) deep notches
into both sides of the door.

D. Insert the latch unit in the door, making certain that the latch bolt
bevel faces the direction of the closing door. Attach with two (2)
#8 combination screws provided.

Note: Use of a drill guide is recommended to ensure
straight and level holes.

IF USING THE FALCON OPTIONAL DRILL GUIDE

Install Drill Guide (M204-198) into the door. Make certain the
correct backset locators are even with door edge. Drill two (2) ⁵⁄₁₆" (8 mm)
holes from both sides to the center.
