It includes a spring-controlled damper that closes automatically when the connected appliance is not running, blocking outside air, pests, and debris from entering the duct system. A built-in screen adds a secondary barrier against insects and small animals. The cap is constructed from aluminum for corrosion resistance in outdoor installations. HVAC technicians and sheet metal contractors install this fitting during new construction and retrofit projects where a clean, weather-resistant duct termination is required.\u003c\/p\u003e\n\u003cp\u003eThis wall cap is suited for residential and light-commercial exhaust applications including dryer vents, bathroom exhaust fans, kitchen range hood venting, and HRV or ERV terminations. It is designed for through-wall installation on exterior surfaces where 6-inch round duct terminates. The spring-controlled damper ensures the duct remains sealed when airflow is absent, which is important in cold climates where backdraft and freezing are concerns.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpring-controlled damper closes automatically when airflow stops, preventing backdraft and outside air infiltration\u003c\/li\u003e\n  \u003cli\u003eBuilt-in screen blocks insects, birds, and debris from entering the duct\u003c\/li\u003e\n  \u003cli\u003eAluminum construction resists corrosion for long-term exterior use\u003c\/li\u003e\n  \u003cli\u003eFits 6-inch round duct — a common size for dryer, range hood, and ventilation fan exhaust\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit ready for installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation wall cap for 6-inch round exhaust duct terminations on residential and light-commercial ventilation systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by an HVAC technician or sheet metal contractor following local mechanical code requirements. Shut off and disconnect the appliance connected to the duct before beginning any duct termination work. The cap should be sealed to the exterior wall surface with an appropriate weatherproof sealant to prevent water infiltration around the penetration. Verify that the damper swings freely and the screen is clear of obstructions after installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Type\u003c\/strong\u003e: Spring-controlled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScreen\u003c\/strong\u003e: Included\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.26 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 each\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LAMBRO INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 346S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LAMBRO INDUSTRIES","offers":[{"title":"Default Title","offer_id":51523406594354,"sku":"346S","price":49.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/67c0b15338d8f0386139172066a3895c.jpg?v=1785441988","url":"https:\/\/voomisupply.com\/products\/lambro-industries-346s-aluminum-wall-cap-6-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
