MODEL 500/505 INSTALLATION INSTRUCTIONS
The model 500/505 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 square. Any lock and
key mechanism is retained to operate the deadbolt. The latchbolt will only
operate by code, and NOT by key.
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
500/505 lock plates.
IF YOUR LOCKCASE HAS A
HOLE BELOW THE
FOLLOWER (FIGURE 1 ‘A’),
PROCEED AS FOLLOWS:
step 1
Hold one of the black
neoprene seals against the
door, perfectly vertically, with
the large hole accurately 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 both points drill a 12mm
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
diameter. Replace the lock.

step 2
Take the 2-part spindle, with
the springs in place. Note that
one has a RED coloured face,
and the other a BLUE face. If
your door is hinged on the
right, viewed from outside,
then fit the BLUE spindle into
the latch follower on the
outside, with the colour on
TOP. Fit the RED spindle to
the inside, again with the
colour on TOP. For a left hand
hung door fit the spindles the
other way around, with the
colours on TOP.
step 3
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 4
Cut two of the black socket
head screws to the required
length for your door.
Approximate overall length
should be door thickness plus
25mm, to allow about 10mm
of threaded bolt to enter the
outside plate.
step 1
Hold one of the black
neoprene seals against the
door, perfectly vertically, with
the large hole accurately over
the follower. Mark the top hole
and the holes on either side
of the follower, and then
repeat the procedure on the
other side of the door.
Remove the lock.
Drill the 3x 12mm holes 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.
step 5
Apply the front and back
plates, with the neoprene
seals in position, against the
door, over the protruding
ends of the spindle.
step 6
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 using the ‘T’ shaped
Allen key. Do not use
excessive force.
step 7
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.
IF YOUR LOCKCASE ONLY
HAS HOLES ON EITHER
SIDE OF THE FOLLOWER
(FIGURE 1 ‘B’), PROCEED
AS FOLLOWS:
step 2
Take the 2-part spindle, with
the springs in place. Note that
one has a RED coloured face,
and the other a BLUE face. If
your door is hinged on the
right, viewed from outside,
then fit the BLUE spindle into
the latch follower on the
outside, with the colour on
TOP. Fit the RED spindle to
the inside, again with the
colour on TOP. For a left hand
hung door fit the spindles the
other way around, with the
colours on TOP.
