APPENDIX A: INSTRUCTIONS FOR DOOR AND FRAME PREPARATION OF CYLINDRICAL LOCK
A. CHECKLIST
Tools for Door Preparation
 Drill
 Drill Bits: 1” (31/32” for drive in latch), 5/16”
 Hole Saw: 2-1/8”
 Phillips Screwdriver, #2
 Hammer
 Chisel
B. DOOR PREPARATION
1. Doors: Steel or Wood
2. Door thickness range: 1-3⁄8" (35mm) ~ 2" (51mm).
3. Match the Backset of your Proxess CX-Series lockset to the corresponding installation (either 2-3⁄8" [60 mm] or 2-3⁄4" [70
mm] Backset).
4. Place the installation template onto the door and mark holes. Drill the 2 1⁄8" (54 mm) first, then drill the two 5/16" (8mm)
holes for lock chassis mounting. Drill the 1" (25 mm) cross bore hole for the latch last.
5. Insert latch into 1" hole and hold it parallel to door face, mark outline and remove latch. Chisel 11⁄64" (4.3mm) deep or
until faceplate is flush with the edge of the door. Insert latch into the 1" hole again, making certain that the latch bolt bevel
faces direction of closing door (see section E for Lock Handing).
6. Secure the latch to the door using two #8x3/4" screws (SP2).
NOTE: Removing the through bolt posts from the chassis will decrease the security of the lock, voiding ANSI
Grade 1 rating of the lock.
C. FRAME PREPARATION
1. Close the door and mark the horizontal line aligned to the strike.
2. Measure one half of door thickness from door stop to mark vertical center line of strike. Drill 1" (25 mm) hole, 1/2" (12.7
mm) deep at intersection of horizontal and vertical center lines.
3. Chisel out the jamb 3/32" (2.4mm) deep or until strike is flushed with jamb and then secure the strike to the jamb using two
#12-24 x 1” screws (SP3).
