MINI-TRUNKING

MINI-TRUNKING INSTALLATION PLANNING
GT1-6 inc. GT8 are available with a full range of moulded fittings. To maintain insulated
integrity when using moulded fittings, the trunking base should be mitred at the corners.
If cabling is to be double insulated, square cut or butt corners can be made, the moulded
fitting will mask the butt joint.
External clip-over couplers are available for GT1, GT2 and GT8. All other mini-trunking
uses internal couplers, where internal couplers are used the trunking cover should over-
run the joint between two body sections.
Eg:
The trunking base should be cut to the required length and fixed to the wall, ceiling etc.
After fitting the base, the cabling can be installed using the moulded fittings to retain the
cables in the base. The trunking cover should be cut to suit.
Fit the cover adjacent to one fitting and slide under the fitting to the location tab. Press
home the cover along the base, guiding the free end under the next fitting, and press
home the cover to complete the installation.
