The straight duct is the workhorse of the system: a rigid PVC channel that runs along the wall carrying the insulated copper pair, the power cable and the condensate drain. It is supplied in standard lengths and can be cut on site, so the same section handles a short balcony run and a full facade. This fitting is supplied in brown, moulded from the same colour-through PVC as the brown kit, so joints and corners stay invisible on the wall.

Brown answers the most common problem on traditional homes: dark brick, timber cladding and wood-grain fascia boards that no standard colour can match. The straight duct section sits quietly against these surfaces, and because the tone is mixed into the PVC itself it weathers at the same rate as the rest of the kit. On brick exteriors it is common to run the trunking vertically past a brick course; the brown finish keeps that run discreet without repainting anything on the wall.
Q: Can straight duct sections be cut to length?
A: Yes. Cut the section with a fine-tooth saw and finish the cut end with an end cap, or join two sections with a coupling.
Q: Which profile widths do you supply?
A: The straight duct is produced in the 75 mm slim profile.
Q: How is the duct fixed to the wall?
A: The base channel is screwed to the wall at intervals and the cover snaps on afterwards, so the line set can be laid in before closing.
