A System100 roof vent cowl for Ø110mm pipe in grey, used to terminate a ventilation duct run through a pitched roof. The cowl provides a weatherproof external termination point, preventing rain, debris, and birds from entering the ductwork while allowing exhaust air to escape freely. The grey finish suits slate, fibre cement, and grey concrete roof tiles.

Compatible with Ø110mm round ductwork. Supplied as a single unit.
