Constructed with a steel blade, this damper provides durable, repeatable airflow control at the diffuser neck. The 9-inch round configuration fits standard 9-inch diameter duct connections. It includes a removable adjustable handle, allowing technicians to set the blade position during balancing and remove the handle for a clean finished appearance. HVAC technicians and sheet metal installers use this type of damper during system commissioning to manually balance airflow across zones.\u003c\/p\u003e\n\u003cp\u003eThis damper is suited for residential and light commercial HVAC installations where T-bar lay-in diffusers are used in suspended ceiling grids. It is installed at the neck of the diffuser to restrict or open airflow to individual supply outlets. The round butterfly style is commonly used in systems where round flex duct or round rigid duct connects directly to the diffuser boot. The removable handle makes it practical for installations where a finished ceiling appearance is required after balancing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9-inch round configuration fits 9-inch diameter duct necks\u003c\/li\u003e\n  \u003cli\u003eSteel blade construction for durability in supply air applications\u003c\/li\u003e\n  \u003cli\u003eButterfly-style damper provides simple, effective airflow restriction\u003c\/li\u003e\n  \u003cli\u003eRemovable adjustable handle allows balancing and clean post-install appearance\u003c\/li\u003e\n  \u003cli\u003eDesigned for use with T-bar ceiling diffusers in suspended grid ceilings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation butterfly damper for 9-inch round T-bar ceiling diffusers in residential and light commercial ducted HVAC systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or sheet metal installer. The system fan should be off and the circuit de-energized before accessing the diffuser assembly. The damper is set to the desired position during air balancing, after which the handle may be removed. Follow local mechanical codes and SMACNA guidelines for diffuser and balancing damper installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Size\u003c\/strong\u003e: 9 inches diameter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Type\u003c\/strong\u003e: Butterfly, Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInclusions\u003c\/strong\u003e: Removable adjustable handle\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: HART COOLEY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 050293\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HART \u0026 COOLEY","offers":[{"title":"Default Title","offer_id":51283919044914,"sku":"50293","price":31.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277704.jpg?v=1781063253","url":"https:\/\/voomisupply.com\/products\/hart-cooley-050293-t-bar-diffuser-butterfly-damper-9-in","provider":"Voomi Supply","version":"1.0","type":"link"}
