Constructed in black plastic, it provides a weather-resistant cap that prevents backdrafts, pests, and moisture intrusion while allowing exhaust air to escape. This type of fitting is a standard finish component in residential bath ventilation systems and is typically installed by roofers, HVAC technicians, or general contractors during new construction or exhaust fan upgrade projects.\u003c\/p\u003e\u003cp\u003eThis roof vent cap is suited for residential bathroom exhaust applications where a 4-inch duct terminates through the roof deck. It is commonly used in single-family homes and light residential construction to cap bathroom fan duct runs that exit through the roofline rather than through a soffit or exterior wall. The black finish is appropriate for installations on dark-colored roofing materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-inch duct connection sized for standard bath exhaust fan ductwork\u003c\/li\u003e\n\u003cli\u003eBlack plastic construction resists corrosion and weathering\u003c\/li\u003e\n\u003cli\u003eRooftop installation design prevents backdraft and moisture entry\u003c\/li\u003e\n\u003cli\u003eLightweight plastic body simplifies handling and cutting during install\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation roof termination cap for standard 4-inch residential bathroom exhaust duct systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or qualified roofer. Shut down the connected exhaust fan at the circuit breaker before beginning work. The roof penetration should be properly flashed and sealed per local building code requirements to prevent water infiltration around the vent collar. Avoid compressing or kinking the connected duct run, as this reduces airflow and exhaust fan performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Roof termination for bathroom exhaust ventilation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VENTI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PBRV04\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VENTI AIR PRODUCTS","offers":[{"title":"Default Title","offer_id":51306260791602,"sku":"PBRV04","price":28.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309549454.jpg?v=1781287687","url":"https:\/\/voomisupply.com\/products\/venti-pbrv04-plastic-roof-bath-vent-4-inch-black","provider":"Voomi Supply","version":"1.0","type":"link"}
