Tab mounting holds the collar securely in the cut opening without fasteners. A built-in scoop directs conditioned air into the branch run, and an integrated damper allows the tech to throttle airflow for balanced air distribution across zones. This fitting is installed by HVAC technicians during new construction duct fabrication or system modification work.\u003c\/p\u003e\u003cp\u003eThe 1729-16 is suited for residential and light commercial HVAC systems where duct board is used as the primary trunk or plenum material. The collar installs into a field-cut round opening, with the mounting tabs folding over the duct board face to lock the fitting in place before connecting round metal pipe or flex duct to the spigot end. The built-in damper gives the installer direct control over branch airflow without adding a separate balancing damper downstream.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e16-inch diameter spin-in collar sized for large branch or main distribution connections\u003c\/li\u003e\n\u003cli\u003eTab mount design locks into duct board without additional fasteners\u003c\/li\u003e\n\u003cli\u003eIntegrated scoop directs airflow into the branch duct for improved delivery efficiency\u003c\/li\u003e\n\u003cli\u003eBuilt-in damper enables airflow balancing at the take-off point\u003c\/li\u003e\n\u003cli\u003eCompatible with round rigid pipe and flexible duct connections\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for duct board HVAC systems requiring a 16-inch round branch take-off connection.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed HVAC technicians. Power down the air handling unit and close the system before cutting into the duct board trunk or plenum. Use a hole saw or duct board knife to cut a clean round opening sized to the collar spigot diameter, then seat the collar and fold the tabs over the duct board surface to secure. Seal all edges with UL 181-rated tape or mastic per local mechanical code requirements before connecting the branch duct.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 16 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: Built-In\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Type Compatibility\u003c\/strong\u003e: Duct Board\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: 1729-16\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SEAL-TITE","offers":[{"title":"Default Title","offer_id":51342929854770,"sku":"1729-16","price":64.49,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554812.jpg?v=1782010931","url":"https:\/\/voomisupply.com\/products\/seal-tite-1729-16-duct-board-spin-in-collar-16-in-tab-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
