The collar drops into a field-cut round opening in the duct board and locks in place using integrated mounting tabs for a stable, rattle-free fit. A built-in scoop directs conditioned air from the main duct into the branch run, improving airflow transition. The integrated damper blade allows the technician to balance airflow at each branch without adding a separate balancing damper downstream.\u003c\/p\u003e\u003cp\u003eThis collar is used in residential and light commercial forced-air HVAC systems where duct board is the primary trunk or plenum material. It is suited for new construction and retrofit installations where a branch takeoff is needed for a supply run serving a room or zone. HVAC technicians and sheet metal installers are the typical trade installing this fitting. The 14-inch size fits high-volume supply branches or larger room loads.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e14-inch round opening for connection to round pipe or flex duct\u003c\/li\u003e\n\u003cli\u003eTab mount design secures collar in duct board without additional fasteners\u003c\/li\u003e\n\u003cli\u003eIntegrated scoop promotes smooth airflow transition into the branch\u003c\/li\u003e\n\u003cli\u003eBuilt-in damper allows on-site airflow balancing at the collar\u003c\/li\u003e\n\u003cli\u003eSpin-in installation drops into a cut opening for fast field assembly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style fitting for duct board trunk and plenum systems requiring a round spin-in branch collar connection.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified sheet metal installers. Power down the air handler and set the thermostat to off before cutting into an existing duct board system. Use a round hole saw or duct board knife sized to the collar diameter, and ensure the cut opening is clean and square before inserting the collar. Seal the perimeter of the collar flange to the duct board with UL 181B-rated tape or mastic to prevent air leakage at the joint.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollar Diameter\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Tab Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAirflow Feature\u003c\/strong\u003e: Scoop\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamper\u003c\/strong\u003e: Integrated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Style\u003c\/strong\u003e: Spin-In\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: 1729-14\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SEAL-TITE","offers":[{"title":"Default Title","offer_id":51342760509746,"sku":"1729-14","price":59.6,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554819.jpg?v=1782005788","url":"https:\/\/voomisupply.com\/products\/seal-tite-1729-14-spin-in-collar-14-in-tab-mount-with-damper","provider":"Voomi Supply","version":"1.0","type":"link"}
