Quadrant dampers use a rotating blade controlled by an external quadrant handle, allowing technicians to manually set and lock airflow to individual branch runs or zones. This damper is installed in round or rectangular duct takeoffs where balancing or shutoff control is needed. HVAC installers and sheet metal contractors work with this type of component during new construction, system balancing, and duct retrofit projects.\u003c\/p\u003e\n\u003cp\u003eThe 10669 is suited for round duct branch balancing applications in forced-air heating and cooling systems. It is typically installed at the trunk-to-branch junction or within a straight duct run where manual volume control is required. The 9-inch size fits standard 9-inch round duct, making it a straightforward fit in common residential trunk-and-branch layouts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9-inch diameter fits standard round duct branch runs\u003c\/li\u003e\n  \u003cli\u003eQuadrant handle allows manual airflow adjustment and lockout\u003c\/li\u003e\n  \u003cli\u003eDesigned for volume control and balancing in forced-air duct systems\u003c\/li\u003e\n  \u003cli\u003eSheet metal construction consistent with standard HVAC duct fabrication practices\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation component for 9-inch round duct systems in residential and light commercial forced-air HVAC applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or sheet metal contractor. The air handling system should be shut down before installing or adjusting the damper. Secure the damper to the duct with sheet metal screws and seal all joints with approved duct tape or mastic per local mechanical code requirements. Do not restrict the quadrant handle range of motion after installation, as this is the primary means of airflow adjustment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Quadrant Damper\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: 10669\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283917439282,"sku":"10669","price":20.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277373.jpg?v=1781063212","url":"https:\/\/voomisupply.com\/products\/southwark-metal-10669-quadrant-damper-9-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
