Stainless steel wall cowls provide a durable, weather-resistant external termination for ventilation ductwork. The square hood protects the opening from rain and wind, while available insect-mesh, backdraft-flap or combined mesh-and-flap options allow the cowl to be matched to the application. Brushed stainless steel construction and a sealing gasket provide a clean, corrosion-resistant finish suited to residential, commercial and exposed environments.
