Description

This Knightsbridge aluminium ducting kit provides 3.3m of flexible 100mm diameter duct with two stainless steel jubilee clips for securing the duct to extraction equipment or ventilation fittings. The aluminium construction allows the duct to expand and compress along its length, making it easier to route through tight spaces or around obstacles during installation.

Designed for residential and light commercial ventilation applications, the kit suits extractor fans in kitchens, bathrooms and utility rooms, inline fans for loft ventilation, and portable air conditioning units that require an exhaust run to a window or external vent. The 100mm internal diameter matches common UK extractor fan outlet sizes, and the supplied jubilee clips fit securely over the corrugated exterior to create an airtight seal at each connection point.

The aluminium foil and wire construction is lightweight enough to be supported by standard duct brackets or cable ties without sagging, while remaining puncture-resistant during installation through wall cavities or ceiling voids. The duct can be compressed to approximately 600mm for transport and storage, then extended to the full 3.3m length on site. The 110mm cut-out diameter specification refers to the outer diameter of the corrugated profile, allowing clearance when passing the duct through wall apertures or ceiling grilles.

Frequently Asked

What are the jubilee clips for?

The two stainless steel jubilee clips secure each end of the duct to the extractor fan outlet and the external vent or grille. Tighten them with a screwdriver to create an airtight seal and prevent the duct from slipping off during operation.

Can the duct be cut to a shorter length?

Yes. The aluminium foil and wire construction can be cut with heavy-duty scissors or tin snips if you need a shorter run than 3.3m. Cut cleanly across the corrugations to avoid fraying the edges.

Is the duct suitable for high-temperature applications?

Standard aluminium ducting handles air temperatures up to approximately 120°C, which covers typical kitchen extractor and bathroom fan applications. It is not suitable for direct contact with boiler flues or high-temperature industrial extraction.

What size extractor fan does this fit?

The 100mm internal diameter matches most 4-inch outlet extractor fans commonly used in UK residential installations. Check your fan's outlet diameter before ordering to ensure compatibility.
