The flexible corrugated section absorbs misalignment between the trunking run and the unit connection. It compresses, extends and bends slightly, covering the last awkward centimetres that rigid sections cannot. Supplied in white, moulded in the same colour-through finish as the white classic kit, so the fitting blends into the run instead of standing out.

The white finish was developed for the light-coloured facades that dominate new housing. Against white render or a cream-painted wall, the flexible corrugated duct all but disappears, keeping the exterior line clean without repainting to match. The pigment is mixed into the PVC before moulding, so the colour survives UV exposure, rain and ladder contact far better than a sprayed finish. Installers who cover large housing estates usually standardise on white for exactly this reason, then order replacement flexible corrugated duct units from the same production batch.



Q: Does this fitting fit the current slim series?
A: No. The classic rounded profile is wider and rounder than the current series, so fittings only match within the same generation.
Q: Which sizes does it suit?
A: The classic series is produced in 110, 130 and 160 sizes. Order the fitting against the trunking width used on site.
Q: Can it be ordered without a full kit?
A: Yes. Individual components are available for replacement, extension and bulk stock orders.
