Instructions:
CAUTIONS: Do not unscrew small retaining screws at rear of cylinder. Use only dry lubricant (graphite) on locks. Keep away clear of foreign objects.

To Install:
1. Select convenient  height for lock and place template against edge of door.
2. Mark hole positions. Bore 1-3/8″ hole for cylinder where indicated. Note: Bore through door until tip of drill barely emerges from other side. Remove drill bit and complete hole by drilling from opposite side to reduce splintering.
3. Drill 3/32″ diameter holes 1/2″ deep from attachment screws.
4. Insert cylinder and trim ring from outside of door. Attach backplate with two connecting bolts. Note: If bolts are too long, saw or break at groove, using caution to avoid marring the thread.
5. Cut or break connecting bar so it projects 3/8″ to 1/2″ beyond the inside of the door.
6. Plack lock on door so connecting bar enters “X” slot in back of lock. Secure with large mounting screws.
7. Align strike carefully, using template as a guide. Draw outline of strike on door jamb trim and chisel wood away (mortise) so strike mates freely with locking bars.
8. Mark mounting homes for strike, dill pilot holes, and secure strike to door jamb with screws provided.
