Mounting Boxes
Due to the slimline design MK Edge accessories
require deeper back boxes than standard. They
are designed to fit into folded metal boxes that
comply with BS 4662. To ensure products can
be correctly installed, the box must always be
installed flush or sub flush to the surface to a
maximum depth of 6mm.
The recommended depth of boxes for the
different types of wiring accessories are as
follows:

*Note: If Grid system accessories are to be fitted and
the installation requires the attachment of conduit via
nuts inside the mounting box, then it is recommended
that a box depth of 47mm is used.
Fixing Screws
The surface head of Edge fixing screws is
treated and compliment the finish of the
frontplate. To prevent damage to the fixing screw
extreme care is required. It is recommended that
a screwdriver with a maximum blade of 3.5mm
is used.
