Note: Space required above latch body for cam to rotate.
Step 2
Keeping the drill level and square to the door, drill a 25mm (1”) hole in centre of door edge, deep enough to
accept the latch.
Step 3
Keeping the drill level and square to the door, drill the 10mm and 30mm ( ⁄ ”- 1 ⁄ ”) holes from both sides
of the door to increase accuracy and to avoid splintering out the door face.
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.
Step 6
Fitting the strike plate. N.B. 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
Take the BLUE or RED tipped spindle and fit to the code side according to the hand of your door (see
diagram).
Fit remaining spindle to inside - non code side.
Step 8
Fit the 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 9
Cut three of the socket head bolts to the required length for your door. Approximate overall length should
be door thickness plus 25mm (1”) to allow about 10mm ( ⁄ ”) of threaded bolt to enter the outside plate.
Step 10
Apply the front and back plates, with the neoprene seals in position, against the door, over the protruding
ends of the spindle.
