PBS1 & PBS2 British Standard Nightlatch
Fitting Instructions
1. Choose the correct side of the ‘Cylinder Pull’ template for your door, depending on whether it is hinged on
the left or right, as seen from inside.
2. At the height you want your lock, use the ‘Cylinder Pull’ template provided to mark the three holes
indicated on both sides of the door. At the middle mark, drilling from both sides of the door, drill a 32mm
diameter hole through the door.
2a. Working from the outside of the door, drill a 13mm diameter hole to a depth of 16mm at each of the two
other marked spots.
(DIY TIP: Mark your drill bit with sellotape or other coloured adhesive material at the required drill depth)
2b. Working from the inside of the door, drill a 13mm diameter hole to a depth of 5mm at each of the two
marked spots.
2c. From the inside of the door, drill 8mm diameter holes through the centres of the two holes you drilled in
Steps 2a and 2b.
3. Using your ‘Mounting Plate’ template, mark the position of the three small holes, as indicated, on the
inside of the door. Drill three 3mm diameter holes to a depth of 32mm at the spots you’ve marked.
4. Using your ‘Mounting Plate’ template, mark the outline of the recess, as indicated, on the edge of the
door.
5. Line up the top and bottom of the projecting kitemarked panel of the lock body with the top and bottom of
the recess outline you’ve just drawn. Mark the outline of the panel on the door edge.
6. Using a hammer and a sharp chisel, cut out the shape of the panel to a depth of 3mm.
7. Place the lock body on the back of the door so that the projecting kitemarked panel sits in the recess
you’ve just cut out. Mark the position of the two screw holes in the panel on the door edge. Drill two 3mm
diameter holes to a depth of 25mm at the spots you’ve marked.
8. With the key removed, position the cylinder/door pull assembly in the door, with the flat connecting bar
sticking out from the back of the door. If necessary, use a fine-toothed hacksaw to shorten the flat
connecting bar so that it projects 4mm beyond the surface of the door.
9. Screw the cylinder/door pull to the door using the large cross-headed bolts provided. You may need to
shorten them with a fine-toothed hacksaw to make sure they are sunk below the door surface in the holes
which you drilled for that purpose in Step 2. Tighten the bolts so that the door pull does not move.
