125mm Branch

Our 125mm curved boot saddles give you a 125mm (approx. 5″) diameter branch off a main spiral duct run. The curved (swept) boot profile eases air from the main spiral duct into the branch, making it a popular take-off for dust and fume extraction systems. Every fitting on this page has a 125mm branch outlet, to suit main duct diameters from 125mm to 1000mm (22 sizes) — just pick the option matching your main duct. Alpha Air is a Leicester-based ventilation supplier — main-duct sizes up to 315mm are stocked for next-day delivery when ordered by 3pm; larger sizes are made to order and despatched in 2-3 working days.
