It provides a flexible, code-compliant transition from a rigid or semi-rigid duct run to a soffit exhaust point, handling the final connection between the ductwork and the exterior termination. The UL 181 Class 1 rating confirms the connector meets fire, airflow, and pressure requirements recognized by mechanical codes. HVAC technicians and installers use this kit when routing bathroom exhaust fans, kitchen range hoods, or dryer vents through a soffit termination in residential applications.\u003c\/p\u003e\n\u003cp\u003eThis kit is suited for residential ventilation installations where a 4-inch duct system terminates at a soffit. Typical applications include exhaust fan duct runs in bathrooms, utility rooms, and laundry areas. The 8-foot length provides enough reach to bridge the joist bay and connect the interior duct to the soffit cap without field-splicing additional connector sections. It is packaged individually and sold per each unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUL 181 Class 1 Air Connector rating for code-compliant residential duct terminations\u003c\/li\u003e\n  \u003cli\u003e4-inch diameter fits standard exhaust fan and ventilation duct connections\u003c\/li\u003e\n  \u003cli\u003e8-foot length accommodates typical joist bay runs without splicing\u003c\/li\u003e\n  \u003cli\u003eDesigned for soffit termination applications in residential construction and retrofit work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation connector for 4-inch residential exhaust ventilation duct systems terminating at a soffit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified mechanical contractors in accordance with IMC and local mechanical code requirements. Power to the exhaust fan or appliance must be shut off at the breaker before disconnecting or connecting ductwork. Secure both ends of the connector with approved duct clamps or foil tape rated for air duct applications. Do not compress or kink the connector during routing, as restrictions reduce airflow and can cause moisture buildup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 8 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertification\u003c\/strong\u003e: UL 181 Class 1 Air Connector\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7.7 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: 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: 144W-K\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LAMBRO INDUSTRIES","offers":[{"title":"Default Title","offer_id":51523954114866,"sku":"144W-K","price":141.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a205e29e073314783d0d578665bdb535.jpg?v=1785444528","url":"https:\/\/voomisupply.com\/products\/lambro-industries-144w-k-soffit-vent-kit-4-in-x-8-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
