Code Locks CL400 Series Front Plates
Installation
The model 410/415 has a tubular, deadlocking, mortice latch and may be used as a new installation on a door, or where an existing latch is to be replaced.
Step 1
Lightly mark a height line on the edge and both faces of the door, and on the
door jamb, to indicate the top of the lock when fitted. Crease the template
along the ‘fold along the door edge’ dotted line that suits your latch
backset, and tape it to the door. Mark the 2 x 10mm (3⁄8″) and the 4x 16mm
(5⁄8″) holes. Mark the centre of the door edge centre line of latch. Remove
the template and apply it to the other side of the door, aligning it
accurately with the first central line of the latch. Mark the 6 holes again.
Step 2
Keeping the drill level and square to the door, drill a 25mm hole to accept
the latch.
Step 3
Keeping the drill level and square to the door, drill the 10mm (3⁄8″) and 16mm
(5⁄8″) holes from both sides of the door to increase accuracy and to avoid
splintering out the door face. Clear a 32mm square hole from the 4 x 16mm
holes.
Step 4
Put the latch into the hole and, holding it square to the door edge, draw
around the faceplate. Remove the latch and score the outline with a Stanley
knife to avoid splitting when chiselling. Chisel a rebate to allow the latch
to fit flush to the surface.
Step 5
Fix the latch with the wood screws, with the bevel towards the door frame.
Step 6
Fitting the strike plate.
Note: The plunger beside the latch bolt deadlocks it, to protect against
manipulation or ‘shimming’. The strike plate must be accurately installed so
that the plunger CAN NOT enter the aperture when the door is closed, even if
it is slammed shut. Position the strike plate on the door frame so that it
lines up with the flat of the latch bolt, and NOT the plunger. Mark the
positions of the fixing screws, and draw around the aperture of the strike
plate. Chisel out the aperture 15mm deep to receive the latch bolt. Fix the
strike plate to the surface of the frame using only the top fixing screw.
Gently close the door and check that the latch bolt enters the aperture
easily, and is held without too much ‘play’. When satisfied, draw around the
outline of the strike plate, remove it and cut a rebate to enable the
faceplate to lie flush with the surface. Re-fix the strike plate using both
screws.
Step 7
Check that the lever handles are correctly fitted for the hand of the door. To
change the hand of a lever handle, loosen the grub screw with the small Allen
key, reverse the lever handle and fully tighten the grub screw.
Step 8
For door hung on a RIGHT fit silver spindle on the code side.
For door hung on LEFT fit coloured spindle on the code side.
Fit the butterfly spindle to the inside, non-code side.
Step 9
Fit latch support post into the back of the code side front plate according
to the hand of your door, A for a right-hand door, or B for a left-hand door
(see diagram). 
Step 10
Cut two of the fixing bolts to the required length for your door. The
approximate overall length should be door thickness plus 20mm (13⁄16”) to
allow about 10mm (3⁄8”) of the threaded bolt to enter the outside plate.
Step 11
Apply the front and back plates, with the neoprene seals in position, against
the door, over the protruding ends of the spindle.
Step 12
Fix the two plates together using the fixing bolts, starting with the top
fixing. Ensure that the two plates are truly vertical and then tighten the
bolts. Do not use excessive force.
Step 13
Before closing the door, enter the code and ensure that the latchbolt will
retract when the lever handle is depressed. Now check the operation of the
inside lever handle. If there is any binding of the handles or latch then
loosen the bolts slightly and reposition the plates slightly until the correct
position is found, and then re-tighten the bolts.
