MODEL CL600/605 INSTALLATION INSTRUCTIONS
The model CL600/605 is intended to replace the conventional door furniture
fitted to an existing mortice latch, or an existing mortice lock which has both a
spring latch and a deadbolt. The square follower should be 8mm ( 5 /
16
”) square.
Any lock and key mechanism is retained to operate the deadbolt.
The CL600/605 will only operate the latchbolt and not the deadbolt.
A mortice lock case should have holes for fixing bolts to pass through on
either side of the square latch follower and sometimes, additionally, a hole
below the follower. See figure 1 and confirm that your lockcase is compatible
with the CL600/605 lock plates.
IF YOUR LOCKCASE HAS A HOLE
BELOW THE FOLLOWER (FIGURE
1 ‘A’), PROCEED AS FOLLOWS:
STEP 1
Hold the neoprene seal with
the three fixing holes against
the door, vertically, with the
rectangular hole centrally
over the follower. Mark the
top and bottom holes on the
door face, and repeat the
procedure on the other side
of the door. Remove the lock.
At three points drill a10mm
( 5 /
16
”)
( 3 /
8
”) hole through the door.
Drill from both sides for greater
accuracy and to avoid
splintering out of the door
face. Check that the existing
spindle hole is at least 18mm
(
3 /
4
”) diameter. Refit the lock.
IMPORTANT: When using CL600/CL605 front and back plates only, please test with your
selected lock-case to ensure that the latch retracts fully from the code side without too much
resistance.
Some lock-cases have a heavily sprung latch follower designed for use with un-sprung lever
furniture. This heavy springing can defeat the clutch on our locks.
Please note the code chamber for mechanical locks requires the lever to be rotated at least
45 degrees to re-set the lock for the next code user.
Please contact our Codelocks technical department if you are unsure. Codelocks Limited does
not accept responsiblilty for products incorrectly specified.
