Technical specifications
Material
PVC-U is flame retardant and self-extinguishing. It provides a 100% recyclable material with good sustainability.
Expansion/Contraction
PVC-U expands and contracts at a uniform rate of approx 5.25mm in a 3 metre length for a temperature change of 25°C. Therefore, a 3mm gap between each length of trunking base is recommended.
Fittings allow for thermal expansion of the covers.
Fitting
• Secure trunking base in one plane only every 500mm by drilling alternate 6mm holes. Use roundhead screws.
• Avoid over-tightening to permit thermal movement.
• The use of plastic caps over screw heads is recommended to protect installed cables.
• To provide cable segregation, dividing fillets are fixed by adhesive tape to trunking base.
• To cut the trunking, use a fine-toothed panel or power jig-saw.
• External profile fittings overlap joints by up to 10mm to cover cutting inaccuracies.
• A variable angle jig-saw or chop saw is recommended for cutting 45° mitres.
Trunking lengths are connected using internal couplers as
follows:
Cement one end of the internal coupler to one base using adhesive solvent BXSC. Leave other end of coupler free in adjoining base to facilitate thermal movement.
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 & Bends
• Clip-on fittings and 2-part moulded flat angle: base must be mitred at 45˚ to ensure total enclosure of trunking, including any internal fitted segregator.
• Fabricated fittings: a 3mm gap between trunking base and bend or flat angle is recommended.
• External moulded fittings overlap the joints by up to 10mm to cover cutting inaccuracies.
• Maxi fabricated fittings are supplied with internal couplers (see Fitting).
• Secure end caps using solvent adhesive BXSC.
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 cover is butt-joined to the edge of the box. Cut edges of the cover are concealed by the accessory. For external
fitting couplers, the following gaps should be left between the two cover ends to permit the fitting to clip to base:
CT30 20mm
CT40 20mm
CT50 20mm
CT60 20mm
CT70 20mm
Covers Removal
To remove a cover, first detach a coupler or internal/external bend to gain access. The main cover can then be gently eased off the base.
