Aluminium perimeter trunking systems
| 263
Technical information
Material
Aluminium trunking is manufactured
from high precision extruded
aluminium with a powder coat finish.
White RAL 9016
Silver Grey RAL 9006
Installation
Positioning
Suitable for 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 in one plane
only every 500mm by drilling
alternative 6mm holes either side of
divider nib.
• Secure using No 8 round head screws
and washers.
• 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
• Base, covers and metallic fittings to
be cleaned of protective and powder
coatings and earth bonded using
twin earth channel.
• Incoming earth connection is made
using LTB1 bonding assembly.
• Bonding base to base: in final ring or
radial 32Amp circuits, bonding strap
LBS1 can be used.
Joints and bends
• Base joints should be butt jointed
together.
• Internal and external bends are
prefabricated in aluminium, aligned
and butt jointed together so cutting
of base and covers has to be very
accurate to produce a good finish.

Accessory boxes
• Mounted on to trunking body with
accessory external to the trunking.
• Remove required knockout in back
segregator plate that aligns with
trunking cable compartment.
• Clip to trunking base and secure to
wall surface using 2 diagonally
opposite fixing holes.
• Feed cables through knockout.
• After trunking cover has been fitted
to base, clip front cover plate to back
plate.
• Complete assembly is finally secured
together when the wired accessory is
screwed to accessory front plate.

Covers
Covers are designed to limit
unauthorised removal and to remain in
position during normal conditions
irrespective of impact and minor
undulations of the mounting surface.
Covers – fitting
Covers are clipped into place from
front. If accessory boxes are installed,
the LTL1 cover is butt-joined to the
edge of the box mounting. Cut edges
of the cover are concealed by the
accessory. For fittings, a gap of 10mm is
left between the two cover ends to
permit the fitting to clip to base.
Covers – removal
To remove a cover, first detach an
accessory to gain access. The main
cover can then be gently eased off the
base.
Screening
Aluminium containment protects
internal circuits from external
electromagnetic interference. For
internal segregation and screening, use
a screened dividing fillet.

Cable capacities
• All calculations allow for a
45% space factor.
As there can be differences between
data cable sizes, Marshall-Tufflex
recommend that cable dimensions are
confirmedwith themanufacturing
company.
