The reducer coupling steps between two different profile widths, for example where a 75 mm run from the indoor unit widens to 100 mm for a bundle carrying extra cables. It keeps the transition inside the trunking instead of leaving an open gap at the change of size. 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 coupling 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: When do I need a reducer coupling?
A: Wherever two duct sections of different profile widths meet on the same run.
Q: Which size combinations are available?
A: Reducer combinations are produced to order. Confirm the exact pair you need with our sales team before the order is placed.
Q: Does the standard cover still fit over the reducer?
A: Yes. The reducer is closed with the matching covers of each width, so the run stays enclosed.
