Setting out
Mark the vertical and horizontal centre lines on the door
edge. Position the lock clear of the rail joint, or locate the
lock block on hollow core doors. Align the Lock Jig with the
centre lines.
2
Lock body mortise
Fit the relevant mortise template into the jig. Rout out the
mortise in a series of plunge cuts followed by shallow
lateral passes, to straighten the mortise edges.
Trend long reach cutters:
TR37X1/2 TC
TR12X1/4TC

Faceplate recess
Without removing the jig, replace the mortise template with
the faceplate template. Set the depth of cut to suit the
lock/faceplate and rout the recess using the lock itself as a
guide.
4
Fitting the handle and keyhole
Use a paper template to align the spindle positions. Start the
hole from both sides using an auger bit. A scrap of timber in
the mortise will avoid breakout on the inside faces. IP
Spacer fingers are
used to raise the jig
from the door edge
to accommodate
the spigot depth of
the guide bush being
used. Check if these
need to be used by
laying a straight edge
across the underside
of the jig.

An optional corner
chisel can be used to
square the ends of
the faceplate recess.
Given a sharp tap
with a hammer, it will
cut the 90° corner
leaving the waste to
be lifted with a sharp
chisel.
