A System125 ducting kit comprising a flexible hose with gravity flap outlet, measuring Ø125 x 1000mm in white. The gravity flap outlet opens under airflow when the fan operates and closes by gravity when the fan stops, preventing back-draughts and cold air ingress. A practical all-in-one solution for connecting 125mm fans to external wall terminations in kitchen extraction, whole-house ventilation, and commercial applications.

Compatible with System125 and EasiPipe125 Ø125mm round ductwork. Supplied as a single kit.
