This collar creates a secure, snapping connection point at the duct takeoff, allowing installers to quickly attach flexible duct or branch runs without the need for additional fasteners at the collar interface. The 9-inch diameter sizing fits standard round duct openings cut into ductboard panels. HVAC technicians and sheet metal installers use this fitting during new construction and retrofit applications to maintain system integrity and minimize air leakage at branch connections.\u003c\/p\u003e\u003cp\u003eThis snaplock collar is suited for residential and light commercial HVAC installations where ductboard plenum and trunk systems are used. It is typically installed at the point where a round branch duct connects to a ductboard trunk or plenum box. The collar seats into a field-cut hole in the ductboard and locks in place using its integrated snaplock edge, eliminating the need for screws or sheet metal clips at the board interface. The 1.5-inch to 2-inch flange depth accommodates standard ductboard panel thicknesses commonly used in forced-air heating and cooling systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e9-inch diameter fits standard round duct branch openings in ductboard systems\u003c\/li\u003e\n\u003cli\u003eSnaplock design seats and locks into ductboard without additional fasteners at the collar\u003c\/li\u003e\n\u003cli\u003eFlange depth range of 1.5 inches to 2 inches accommodates common ductboard panel thicknesses\u003c\/li\u003e\n\u003cli\u003eProvides a clean, consistent connection point for round flex duct or rigid branch runs\u003c\/li\u003e\n\u003cli\u003eDesigned for low-pressure residential and light commercial forced-air applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style fitting for use with standard fiberglass ductboard panels in residential and light commercial forced-air HVAC systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by licensed HVAC technicians or sheet metal mechanics. Power down the air handling unit and relieve system pressure before cutting into an existing ductboard trunk or plenum. Use a ductboard knife and appropriate hole saw or circle cutter to produce a clean, properly sized opening before seating the collar. Seal all ductboard joints and collar edges with UL 181B-listed mastic or pressure-sensitive tape in accordance with local mechanical codes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollar Diameter\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Depth Range\u003c\/strong\u003e: 1.5 inches to 2 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 122SC-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51306880500018,"sku":"122SC-9","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309549441.jpg?v=1781301237","url":"https:\/\/voomisupply.com\/products\/southwark-metal-122sc-9-ductboard-snaplock-collar-9-in","provider":"Voomi Supply","version":"1.0","type":"link"}
