Constructed from galvanized steel, it features a precision-formed collar that seats tightly against the duct surface, minimizing air loss and maintaining system static pressure. Licensed HVAC technicians install this fitting during new construction duct fabrication or duct retrofit work where a clean, low-leakage branch connection is required.\u003c\/p\u003e\u003cp\u003eThe 301-10 is suited for both residential and light commercial HVAC installations where 10-inch round branch ducts are specified. It performs well in supply-air trunk-and-branch layouts and is appropriate for any forced-air system requiring reliable airflow balance at the takeoff point. The galvanized steel construction holds up in attic, crawlspace, and mechanical room environments where moisture and temperature cycling are common.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e10-inch round collar matches standard round duct branch sizing\u003c\/li\u003e\n\u003cli\u003eGalvanized steel construction resists corrosion in demanding install environments\u003c\/li\u003e\n\u003cli\u003ePrecision-formed collar promotes a tight, low-leakage seal at the branch connection\u003c\/li\u003e\n\u003cli\u003eAirtite design supports system pressure balance and energy efficiency\u003c\/li\u003e\n\u003cli\u003eCompatible with residential and commercial forced-air duct systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting for 10-inch round branch duct connections in residential and commercial forced-air HVAC systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified sheet metal mechanics. Power down the air handler and close the system before cutting into an existing trunk duct. Secure the takeoff collar with sheet metal screws and seal all joints with UL 181-rated duct sealant or mastic per applicable mechanical codes. Avoid relying on duct tape alone as the primary air seal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollar Diameter\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SEAL-TITE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 301-10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SEAL-TITE","offers":[{"title":"Default Title","offer_id":51346808209714,"sku":"301-10","price":25.01,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555056.jpg?v=1782091077","url":"https:\/\/voomisupply.com\/products\/seal-tite-301-10-airtite-takeoff-10-inch-round-duct","provider":"Voomi Supply","version":"1.0","type":"link"}
