It is used to manually regulate or shut off airflow in low-pressure residential and light commercial duct systems. The blade is constructed from hot dip galvanized steel, providing corrosion resistance for long service life in both supply and return air applications. This type of damper is a standard component in forced-air HVAC systems and is typically installed by licensed HVAC technicians or sheet metal contractors during new construction or duct modification work.\u003c\/p\u003e\n\u003cp\u003eThis damper is designed for use in 7-inch round sheet metal ductwork. It suits residential forced-air heating and cooling systems as well as light commercial applications where zone control or branch balancing is needed. The 1-Quad configuration is a common format in trunk-and-branch and radial duct layouts. Installation is straightforward for any sheet metal or HVAC trade professional familiar with standard duct fitting practices.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot dip galvanized steel blade for corrosion resistance in supply and return air applications\u003c\/li\u003e\n  \u003cli\u003e7-inch duct size fits standard round sheet metal duct fittings\u003c\/li\u003e\n  \u003cli\u003e1-Quad damper type for manual airflow regulation or shutoff\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for duct system components\u003c\/li\u003e\n  \u003cli\u003eSuitable for residential and light commercial forced-air HVAC duct systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation damper for 7-inch round sheet metal duct systems built to SMACNA and ACCA standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified HVAC technician or sheet metal contractor. Shut down the air handling unit and confirm zero airflow before cutting into existing ductwork or inserting the damper. Secure the damper in the duct run using sheet metal screws and seal all joints with UL 181-listed mastic or foil tape in accordance with local mechanical codes. Verify damper blade operation and set to the desired position before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Size\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: 1-Quad\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Material\u003c\/strong\u003e: Hot Dip Galvanized Steel\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: 44-1_7IN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284056080690,"sku":"44-1_7IN","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277346.jpg?v=1781067347","url":"https:\/\/voomisupply.com\/products\/southwark-metal-44-1_7in-sheet-metal-duct-damper-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
