Installation Procedure
A) Installing lock in the head of the door
1) Mark the installation position on the top edge of the door.
Diagram 1.
2) Carefully prepare a mortice pocket 85mm x 85mm x
18mm. Take care to ensure the mortice is positioned
centrally in the door as shown at Diagram 2
3) Ensure all debris is removed and check the lock sits
comfortably in the hole all the way to the back of the
fore-end without force.
4) With the bolt extended and the square face plate in
position, mark a pencil line around the face-plate as shown
at Diagram 3. Remove lock and set aside.
5) Using a chisel, remove 4mm of timber inside the pencil line
as shown at Diagram 4, to allow the front of the face plate
to sit flush with the surface of the timber when lock is in
position.
B) Fitting the Escutcheon Assembly
1) Mark a pencil point 57mm from the top of the door and
110mm from the edge of the door as shown at Diagram 5
Using a 22mm flat bit, drill a hole to receive the spindle and
key-drive housing. (Not a through hole - drill one side only).
Re-fit the lock and check to ensure the hole is perfectly
aligned centrally to the square follower.
2) Offer the escutcheon assembly up to the door and mark
the position of the protruding machine screws. Drill two
appropriate holes (6mm) that will enable the plate to sit flat
against the surface of the door as shown at Diagram 6.

3) Using the spindle formula in figure (7) cut the spindle to the
required length, taking care not to trim the end with the through
hole. Align the spindle in the escutcheon assembly and secure
using grub screw supplied. Ensure that the grub screw is fully
tightened using 1.5mm Allen Key as shown at Diagram 8.
4) With the key indent at the 12.00 o'clock position and with the bolt
withdrawn, offer the escutcheon assembly on to the door aligning
the spindle in to the follower on the lock. Test the key to ensure lock
works properly.
5) Using the 2mm drill, carefully drill four pilot holes for the plate
fixings as shown at Diagram 9.
6) Fasten the Escutcheon Plate to the door using 4 x 5/8" No 6 screws.
The plate must be sat firmly back to the surface of the door to
prevent any potential ligature risk.
7) Using the key, operate the lock again to ensure the bolt can be
thrown and withdrawn easily.
8) Using the lock fore-end as a guide, pilot drill two holes and secure
lock and faceplate in position using 2 x 1"¼ No. 8 screws as shown
at Diagram 9.

C) Fitting the Flat Strike Plate
1) With the bolt extended, carefully close the door against the frame
and mark a pencil line on either side as illustrated at 10. Then, using
a Square transfer the lines across the rebate to mark the cut out for
the bolt.
2) With the bolt withdrawn, close the door and inspect the door
alignment in the frame from the inside taking note of any gap or twist.
Then with the door open and bolt extended, measure from the back
edge of the door to the back of the bolt as shown at dimension 'A'
3) Mark dimension 'A' in the frame rebate as shown at Diagram 11
allowing for any gap or twist identified at point 2.
4) Using the markings as a guide, squarely align the strike plate in the
frame rebate and draw a pencil line around the rectangular hole for
the bolt cut out.
5) Using a 13mm flat bit, drill a hole 17mm deep to remove the bulk of
the timber cut out. Afterwards, chisel the residual timber in the
corners away leaving a neat rectangular hole.
6) Close the door and throw the bolt to check the alignment is correct
before fitting the strike.
7) Carefully align the strike plate over the bolt cut out and mark a pencil
line around the plate.
8) Using a chisel, let the strike in to the rebate so that it sits flush with
the surface of the timber.
9) Using a 2mm bit, drill four pilot holes for the strike plate fixings and
secure the strike into position using the 4 x 1 ¼" No 8 screws
supplied.
10) The above technique can be used as a general guide when fitting a
strike plate to timber floor.
See overleaf for installing the lock in the foot of the door.
