STEP 6
Fitting the strike plate.
NB: The plunger beside the latchbolt
deadlocks it, to protect against
manipulation or ‘shimming’. The strike plate
must be accurately installed so that the
plunger CANNOT 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
latchbolt, 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 latchbolt. Fix the strike plate to the surface
of the frame using only the top fixing screw.
Gently close the door and check that the
latchbolt 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 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
Take the BLUE or RED tipped spindle and
fit to the
code side according to the hand
of your door (see diagram).
Fit the butterfly spindle to the inside,
non-code side.
STEP 9
Fit latch support post into 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 back socket head bolts
to the required length for your door.
Approximate overall length should be door
thickness plus 20mm to allow about 10mm
of 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 socket
head 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.
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.
MODEL 410/415 INSTALLATION INSTRUCTIONS
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 dotted line,
and tape it to the door with the top in line
with the height line.
Mark the 2x 8mm and the 4x 16mm holes.
Mark the centre of the door edge on the
Centre Line of Latch. Remove the template
and apply it to the other side of the door,
aligning it accurately with the first Centre
Line of Latch mark. 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 8mm and 16mm 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.
NB Ensure enough room
for the latch support post
NB Space required above
latch body for cam to rotate
