The collar features a snaplock design that allows for quick, secure attachment without the need for additional fasteners. It is sized at 5 inches in diameter and is compatible with ductboard insulation thicknesses from 1.5 inches to 2 inches. HVAC technicians and sheet metal installers use this collar when transitioning between rigid round duct and ductboard plenums or distribution systems in residential and light commercial applications.\u003c\/p\u003e\n\u003cp\u003eThis snaplock collar is used in forced-air HVAC installations where ductboard is the primary duct material. It is typically installed at trunk-to-branch transitions, supply plenum connections, or other locations where a round collar must be inserted into and secured to a ductboard surface. The 1.5-inch to 2-inch insulation thickness range makes it suitable for standard residential ductboard used in attic, crawlspace, and mechanical room applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-inch diameter collar for standard round duct connections to ductboard systems\u003c\/li\u003e\n  \u003cli\u003eSnaplock design enables fast, tool-free engagement for secure fitment\u003c\/li\u003e\n  \u003cli\u003eCompatible with ductboard insulation thicknesses from 1.5 inches to 2 inches\u003c\/li\u003e\n  \u003cli\u003eDesigned for use in residential and light commercial forced-air HVAC systems\u003c\/li\u003e\n  \u003cli\u003eSOUTHWARK METAL construction for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting for ductboard-based forced-air HVAC distribution systems using round collars at 5-inch diameter openings with 1.5-inch to 2-inch ductboard thickness.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified sheet metal installers. Power down the air handling unit and ensure the system is depressurized before working on duct connections. The snaplock collar should be inserted into a clean, properly scored and cut ductboard opening sized to match the collar diameter. Foil tape and mastic sealant applied at the collar-to-ductboard joint are standard practice per SMACNA guidelines to maintain air seal integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollar Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Ductboard Thickness\u003c\/strong\u003e: 1.5 inches to 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Snaplock\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: 122SC-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51306289594674,"sku":"122SC-5","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309549534.jpg?v=1781288243","url":"https:\/\/voomisupply.com\/products\/southwark-metal-122sc-5-ductboard-snaplock-collar-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
