From 280mm
Every spiral duct reducer here has a 280mm large end, stepping down to 7 smaller diameters, from 250mm right down to 125mm. Use one wherever your ductwork steps down in diameter — after a branch take-off, at a fan spigot or where space tightens. Supplied from our Leicester warehouse, with free UK mainland delivery on orders over £400 ex VAT.
For reducers starting from other diameters, see all spiral duct reducers.
