A System100 roof vent cowl for Ø110mm pipe in brown, 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 brown finish blends with traditional clay and concrete roof tiles.

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