Square-to-Round Transition Duct – Made to Measure, Galvanised, DW144
A square-to-round transition (also called a rectangular-to-round adaptor or duct reducer) connects rectangular ductwork – or the outlet of an extraction canopy – to round spiral ducting, fans, silencers and jet cowls. Its smooth tapered body keeps airflow even and noise low. Every transition is made to measure in our Birmingham workshop from galvanised steel, in accordance with DW144 – the UK specification for sheet metal ductwork.
Price
£110 per transition, any size.
