From 762mm
This page groups our 762mm spiral duct reducers — fittings that take a 762mm (30″) duct down to a smaller diameter, stepping down to 7 smaller diameters, from 710mm right down to 400mm. Choose the reducer whose small end matches the next duct size in your system and join it in line with your spiral ducting. Supplied from our Leicester warehouse, with free UK mainland delivery on orders over £400 ex VAT.
