Fabricated from hot dip galvanized steel, this collar provides a secure, airtight transition point where a round branch duct connects to a flat ductboard plenum or trunk. The scoop damper allows field-adjustable airflow balancing at the takeoff point. HVAC installers and sheet metal contractors use this fitting during new construction and retrofit duct installations where ductboard systems require balanced airflow to individual zones or rooms.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for residential and light commercial HVAC applications where ductboard is the primary trunk or plenum material. The spin-in design allows fast, tool-minimal installation directly into a pre-cut ductboard opening. The integrated scoop captures moving air from the main trunk and redirects it into the branch run, improving airflow efficiency at the takeoff. The adjustable damper allows the installer to fine-tune air volume delivery after the system is commissioned, eliminating the need for a separate balancing damper downstream.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e14-inch diameter round spin-in design for direct ductboard installation\u003c\/li\u003e\n  \u003cli\u003eIntegrated scoop improves airflow capture from the main trunk\u003c\/li\u003e\n  \u003cli\u003eAdjustable damper allows balancing without additional downstream hardware\u003c\/li\u003e\n  \u003cli\u003eHot dip galvanized steel construction resists corrosion in conditioned air environments\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for duct construction and airflow\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style fitting for ductboard trunk and plenum systems requiring a 14-inch round spin-in takeoff collar with integrated damper control.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Power down the air handling unit before cutting into any pressurized ductboard section and before inserting the collar. Use a proper ductboard knife and circle cutter to produce a clean, correctly sized opening to ensure a snug spin-in fit and an airtight seal. Follow SMACNA ductboard construction standards and local mechanical code requirements for joint sealing and support spacing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 14 inches diameter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Round spin-in collar\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot dip galvanized steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInclusions\u003c\/strong\u003e: Scoop, damper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ACCA, SMACNA\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: 98WD_14IN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284091633970,"sku":"98WD_14IN","price":75.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277532.jpg?v=1781068335","url":"https:\/\/voomisupply.com\/products\/southwark-metal-98wd_14in-spin-in-collar-scoop-damper-14-in","provider":"Voomi Supply","version":"1.0","type":"link"}
