JIANBENKJ 4-Inch Dryer Vent Cover for Exterior Wall | Hooded Outdoor Exhaust Vent with Damper & Screen

Overview

Shield your outdoor exhaust vents with the JIANBENKJ 4-Inch Dryer Vent Cover. Crafted from durable galvanized steel, this hooded wall vent features a spring-loaded damper and a protective screen to help seal against drafts, pests, and debris when the vent is not in use. Its rugged finish is built to resist rust and corrosion, making it suitable for long-term outdoor exposure on exterior walls, laundry rooms, kitchens, basements, garages, and more.
