This fitting creates a secure, snap-fit connection between rigid fiberglass ductboard panels and round duct, eliminating the need for separate fasteners at the collar joint. The 8-inch diameter and 1.5-inch to 2-inch insertion depth make it suited for residential and light commercial HVAC ductwork fabrication. Sheet metal workers and HVAC installers use this collar when building or modifying ductboard trunk-and-branch systems.\u003c\/p\u003e\u003cp\u003eThis collar is used in ductboard duct systems where round branch takeoffs connect to a fiberglass ductboard plenum or trunk. The snaplock design allows the collar to lock into a field-cut hole in the ductboard, providing a firm mechanical connection without additional hardware. It is a standard fitting for residential forced-air heating and cooling systems where ductboard is the primary duct material. The 8-inch size fits common branch duct runs feeding supply registers in residential construction.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSnaplock design locks into ductboard without additional fasteners at the collar seat\u003c\/li\u003e\n\u003cli\u003e8-inch diameter fits standard round branch duct\u003c\/li\u003e\n\u003cli\u003e1.5-inch to 2-inch insertion range accommodates ductboard thickness variation\u003c\/li\u003e\n\u003cli\u003eDesigned for low-pressure residential and light commercial air distribution\u003c\/li\u003e\n\u003cli\u003eSheet metal construction provides a rigid, stable connection point\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fitting for fiberglass ductboard duct systems used in residential and light commercial forced-air HVAC applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed HVAC technicians or sheet metal workers. Power down the air handling unit and relieve any system pressure before cutting into an existing ductboard system. Use a sharp ductboard knife and the appropriate hole saw or cutting tool sized to the collar diameter to produce a clean hole for proper snaplock engagement. Seal all ductboard connections with UL 181B-rated tape or mastic per local mechanical code requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollar Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsertion Depth Range\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\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Ductboard duct systems\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-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51306329243954,"sku":"122SC-8","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309549445.jpg?v=1781289373","url":"https:\/\/voomisupply.com\/products\/southwark-metal-122sc-8-ductboard-snaplock-collar-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
