It includes a 3-inch tail pipe and a built-in weather damper that closes when the system is not operating, blocking backdrafts, pests, and moisture infiltration. This type of vent is typically installed by HVAC technicians or sheet metal contractors as part of a residential dryer exhaust or bath fan exhaust system. The white plastic construction blends with standard soffit materials and resists corrosion in outdoor exposure.\u003c\/p\u003e\n\u003cp\u003eThis under eave vent is suited for residential applications where duct termination through a vertical or angled soffit face is required. It is commonly used on dryer exhaust runs and bath or kitchen exhaust fan systems where a standard wall cap is not practical due to roof overhang geometry. The 3-inch tail pipe allows direct connection to 3-inch round duct, and the weather damper provides passive backflow control without requiring a motorized actuator. This vent ships in a package quantity of 4 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch face opening sized for standard residential exhaust termination\u003c\/li\u003e\n  \u003cli\u003eIncludes 3-inch tail pipe for direct duct connection\u003c\/li\u003e\n  \u003cli\u003eBuilt-in weather damper blocks backdrafts and pest entry when system is idle\u003c\/li\u003e\n  \u003cli\u003eWhite plastic construction resists corrosion and blends with standard soffit finishes\u003c\/li\u003e\n  \u003cli\u003eDesigned for soffit or eave installation where wall termination is not feasible\u003c\/li\u003e\n  \u003cli\u003eSold in a package of 4 units\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation termination fitting for residential dryer exhaust and bath fan exhaust duct systems using 3-inch round duct connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by an HVAC technician or licensed contractor following local mechanical codes and manufacturer duct termination requirements. Power down or disconnect the exhaust appliance before cutting the soffit opening and securing the vent. Seal the flange to the soffit surface with an appropriate exterior-grade sealant to prevent moisture intrusion. Verify that the weather damper swings freely after installation and is not obstructed by insulation or debris.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace Opening Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTail Pipe Diameter\u003c\/strong\u003e: 3 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: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 4 units\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: 143WTP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LAMBRO INDUSTRIES","offers":[{"title":"Default Title","offer_id":51524082958642,"sku":"143WTP","price":44.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/722c1f051a12b3d7ca19962d5dba6296.jpg?v=1785444981","url":"https:\/\/voomisupply.com\/products\/lambro-industries-143wtp-under-eave-vent-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
