The Premium 6 in Wall Vent is designed to vent exhaust from a kitchen's range hood and bathroom fan to the exterior. This kitchen and bath exhaust vent is built tough in the USA from heavy gauge Galvalume steel with a lighter gauge Galvalume steel damper. The angled, recessed damper with hidden fasteners are engineered to keep its exterior lines simple. The gravity-assisted damper's solid closing action keeps critters outside. With a low profile and clean lines, the 6 in Premium Wall Vent blends in to enhance a home's exterior. Its durable, long-lasting properties stem from a corrosion-resistant powder coated finish that adds weather resistance and a lifetime of shine.
