Introduction
The lock jig is a self centering template used for routing out the edges of doors to
accommodate a variety of popular locks and face plates. The nesting plate is
complete with a clamping lever system which automatically positions the lock centrally
in the door and clamps the jig ready to start routing.
Once the nesting plate is in position, a range of inserts can be added depending on
the size of lock to be fitted. The inserts are used in pairs,- one for the lock body, the
other for the lock face plate.

Assembly
Jig Assembly
The only assembly required is to attach the centralising levers, this is carried out as follows:
1. With the Clarke logo in the nesting plate facing upwards, insert the lever prongs into
the plate slots (Fig. 1).
2. Fit nylon spacer between the lever and nesting plate (Fig. 2)
3. Fit washer on centralising lever (Fig. 3).
4. Secure with wing screw (Fig. 4).
Repeat steps 1 - 4 for other centralising lever on opposite end.

Fig. 3Fig. 4
Finally turn the jig over and fit rubber grips to lever prongs, a light film of liquid soap or
similar applied to the ends of the prongs will assist with this operation.
Before commencing:
ALWAYS ensure the work area is safe and secure.
ALWAYS ensure the door is secured properly, ideally using wedges or similar on both sides
to prevent door moving whilst using the router etc.
ALWAYS ensure the router path is clear of any obstacles etc.
ALWAYS ensure the router power cable is clear of the jig and is of sufficient length.
ALWAYS read and understand the router instruction manual to ensure safe operation.

Using the Jig
Depending on the size of lock to be fitted etc, all that is required is to mark on the door
edge the centre line of the lock position. As a general guideline the centre line would
normally be 1 metre from the bottom of the door.
Once the lock position is determined, mark the centre
line across the door edge (Fig. 5). This mark is used to
position the jig in the correct place for routing.
Loosen both wing screws and turn levers fully
anticlockwise.
Place the jig on the edge of the door, slide into position
so that the centre line on the jig lines up with the marked
centre line on the door edge (Fig. 6).
Turn levers fully clockwise and secure in position by
tightening both wing screws (Fig. 6a), DO NOT overtighten.
Check Jig is in the correct position, once satisfied, carefully
secure the jig to the door edge using suitable woodscews
in the securing holes (3mm ø) top and bottom of the jig.

Before continuing, check that the
centre line on the door is still lined
up with the centre mark on the
nesting plate, if not adjust until it
does.
NOTE: when selecting inserts, take
into account the aperture will cut
approx 1.65mm smaller all round. If
in doubt test on a piece of scrap first.

inserts for the lock to be fitted.
Fit the Insert with the largest

Fig. 7
Fig. 7a
place with locking screw (Fig.
7 & 7a), ensure the insert sits flat
in the nesting plate.
1. Set the router to cut to the thickness of the lock plate + the lock body plate.
2. Position the router onto the jig ensuring the cutter is not touching. Switch the router ON
and plunge to the full preset depth and rout in a clockwise direction until the recess is
completely cut. Switch the router OFF and wait for it to come to a full stop before
lifting it from the jig.
3. Loosen the insert securing screw and remove the insert, DO NOT move the nesting
plate. Square out the recess corners using a sharp chisel.
4. Fit other insert with smaller aperture (lock body) into the nesting plate and secure in
position with locking screw.
5. Set the router to plunge to a maximum depth of 10mm, position the router on the jig as
before. Switch ON and plunge to the full preset depth and rout in a clockwise direction
until the recess is completely cut. Switch the router OFF and wait for it to come to a full
stop before lifting it from the jig.
6. Increase the depth of cut a further 10mm and repeat step 5.
7. Continue to repeat steps 5 & 6 until the required depth is reached, IMPORTANT never
exceed 10mm depth of cut.
8. When the required depth is achieved, switch the router OFF, wait for it to come to a
complete stop, remove the router and store safely.
