Material:stainless steel

Engineered to outperform and outlast. Unlike plastic vents that crack and yellow under UV exposure, our 4-inch vent cover is rust-proof and corrosion-resistant, making it the ideal choice for harsh weather and coastal environments.

GRAVITY FLAP & BACKDRAFT PROTECTION: The integrated weighted flap opens effortlessly for maximum airflow and closes securely to block cold drafts, humid air, and outdoor odors. Perfect for enhancing the efficiency of bathroom fans and kitchen exhaust systems.

PEST & BIRD BARRIER: The cowled square design acts as a natural deterrent against birds, rodents, and large insects looking to nest in your dryer ducts. Keep your ventilation system clean and safe without the lint-clogging risks of fine mesh screens.

UNIVERSAL 4-INCH FIT: Specifically designed for standard 4" (100mm) rigid or flexible ducting. The included rubber gasket ensures a professional, watertight seal against your exterior wall, preventing moisture damage to your home’s facade.
