calimaero HWG 4" Outdoor Dryer Vent Cover – Stainless Steel Wall Vent Hood with Gravity Flap – Weatherproof Exterior Exhaust Fan Cover for Home & Commercial Use – Pest & Draft Protection

• PREMIUM 304 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.
• NOISE-REDUCING & WINDPROOF: Designed with a precision-fit cowl and a cushioned non-return flap to minimize "chattering" or "clapping" noises during windy days. Enjoy a quiet home interior without sacrificing high-velocity air discharge.
• 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.
• 40+ YEARS OF HVAC EXPERTISE: calimaero is a professional brand from a specialized ventilation wholesaler with over four decades of industry experience. We provide expert-grade solutions designed for durability, high performance, and easy installation.
