WARNINGS
Ensure there are no electrical or data cables, gas or water
pipes or other utilities behind the surface before drilling.
Do not drill the holes through the Lockbox.
Do not breathe in the dust created by drilling – it contains
silica which can cause lung disease. Wear respiratory
protection.
a)
Drill the holes with a 10mm masonry drill bit to 90 mm
depth. The quality of the drilled hole is the critical
factor. Ensure the holes are drilled perpendicular to the
fixing plane and that they are sufficiently deep.
a.
If using the 100mm screws, drill the holes to
an 110mm depth
b)
Use the small dustpan to catch the dust from the drilling
or tape a plastic back to the wall underneath where the
holes will be drilled to catch the brick dust.
c)
Sweep brick dust into a polythene bag for use during
deinstallation when filling holes and colouring filler.
