Fabricated from hot dip galvanized steel, it delivers durable corrosion resistance suited for both supply and return trunk duct applications. This reducer maintains structural integrity under typical system static pressures and is built to meet ACCA and SMACNA standards. HVAC installers and sheet metal contractors use this fitting during new construction and retrofit projects where duct sizing changes along the trunk line.\u003c\/p\u003e\n\u003cp\u003eThis reducer is used in residential and light commercial forced-air duct systems where a trunk duct transitions to a smaller cross-section. It is installed inline along sheet metal trunk ducts to manage airflow distribution and maintain system efficiency. The 6-inch size fits standard trunk duct configurations commonly found in central air and gas furnace systems. Sheet metal technicians and HVAC mechanics are the primary installers of this fitting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot dip galvanized steel construction provides corrosion resistance for long-term duct system service\u003c\/li\u003e\n  \u003cli\u003e6-inch size fits standard sheet metal trunk duct configurations\u003c\/li\u003e\n  \u003cli\u003eManufactured to ACCA and SMACNA applicable standards for duct fabrication\u003c\/li\u003e\n  \u003cli\u003eDesigned for inline trunk duct installation during new construction or 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 fitting for sheet metal trunk duct systems requiring a 6-inch reducer transition.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified sheet metal contractors. Power down the air handling unit and close the system dampers before cutting into or modifying an existing trunk duct. Secure the reducer with sheet metal screws and seal all joints with UL 181-listed duct sealant or mastic to prevent air leakage. Follow SMACNA duct construction standards and local mechanical codes for proper fitment and fastening requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dip Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Type\u003c\/strong\u003e: Reducer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUsed On\u003c\/strong\u003e: Sheet Metal Trunk Duct\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ACCA, SMACNA\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: SOUTHWARK METAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 35_6IN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284006994226,"sku":"35_6IN","price":19.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277262.jpg?v=1781065829","url":"https:\/\/voomisupply.com\/products\/southwark-metal-35_6in-trunk-duct-reducer-6-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
