TECHNICAL INFORMATION
Technical information
Material
Aluminium trunking is manufactured
from high precision extruded
aluminium with a powder coat finish.
White RAL 9016
Silver Grey RAL 9006
Accessory boxes are supplied in PVC-U
or polycarbonate both of which are
100% recyclable.
Installation
Positioning
Suitable for dado and skirting installation.
When used as a skirting system, sufficient
clearance should be allowed between
the floor covering and the profile fittings
that clip over the cover i.e. 5mm + floor
covering is recommended.
Fitting
• Secure trunking base every 750mm.
• Secure using No 8 round head screws
and washers using the grooves in the
outer compartments of the base to
facilitate drilling Ø6mm holes.
• Avoid over-tightening to permit
thermal movement.
• The use of plastic caps over screw
heads is recommended to protect
installed cables.
• To cut the trunking, use a fine tooth
blade (32/36tpi) or, preferably,a
circular saw with a 350mm diameter
fine tungsten blade (90/108tpi).
This will produce an edge requiring
minimal de-burring.
• Consecutive lengths of base are
aligned and butt jointed together.
Earthing
• Clean protective coating from base,
covers and metallic fittings and then
earth bond.
• Incoming earth connection is made
using LTB1 bonding assembly installed
in the earth channel of the base.
• Bonding base to base: in final ring or
radial 32Amp circuits, bonding strap
LBS1 can be used.
• Bonding covers and end caps to
base: use bonding strap LBS2.
Single lengths
Where it is required to fit a single
length of trunking (under 3 metres)
between two inside walls and no
accessory box is fitted, it is advisable to
install a coupler in the centre of the run
to facilitate the removal of the cover.
Joints and bends
• Moulded from colour matching
polycarbonate.
• Internal and external bends must
be mitred at 45° to ensure total
enclosure and segregation of
trunking compartments, including
any internal fitted segregator.
• Straight lengths should be butt
jointed together.
• Flat angles and tees are prefabricated
in aluminium.
• Cutting of base and covers is not
critical as external moulded clip-on
fittings cover the joint and overlap
covers by 10mm each side to cover
minor inaccuracies.

Accessory boxes
• For mounting an accessory box in the
alternative compartment to supply,
drill the main web adjacent to the
box position.
• Remove the appropriate knock out
and clip the box into the trunking
base.
• For boxes in the same compartment
as the supply, remove the
appropriate box knock-outs and clip
the box into trunking base.
• When boxes are installed
consecutively, a 14mm wide spacer
(ES1) is required to cover the space
between the boxes.
• Part M box assemblies with
contrasting coloured faceplates are
available to meet the requirements
of DDA regulations for Visual
Impairment.
