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.

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 75, 100, 130 and 160 mm profile widths.
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.
