Fabricated from hot dip galvanized steel, this collar provides a corrosion-resistant, rigid connection point at the ductboard surface. The 1.5-inch tab locks into the ductboard face to create a secure, airtight seat without additional fasteners. The 6-inch diameter opening accommodates standard 6-inch round branch duct. HVAC installers and sheet metal contractors use this collar during new construction and replacement work where ductboard systems require branch takeoffs.\u003c\/p\u003e\n\u003cp\u003eThis collar tap is used in residential and light commercial HVAC duct systems where fiberglass ductboard serves as the main trunk or plenum. It is installed by cutting a matching hole in the ductboard panel, inserting the collar, and folding the 1.5-inch tab flush against the inner surface of the board to lock the fitting in place. The galvanized steel construction holds shape under normal static pressure conditions found in forced-air systems. Sheet metal contractors and mechanical installers working on low-pressure air distribution systems are the primary users of this fitting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot dip galvanized steel construction resists corrosion in conditioned air environments\u003c\/li\u003e\n  \u003cli\u003e1.5-inch locking tab secures the collar to ductboard without separate fasteners\u003c\/li\u003e\n  \u003cli\u003e6-inch diameter fits standard 6-inch round branch duct connections\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for sheet metal duct fittings\u003c\/li\u003e\n  \u003cli\u003eCompatible with typical ductboard trunk and plenum installations\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 residential and light commercial ductboard trunk systems requiring 6-inch round branch collar connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed sheet metal contractors or qualified HVAC technicians. Power down the air handling unit and relieve system pressure before cutting into an existing ductboard trunk. Use a sharp utility knife or ductboard circle cutter to make a clean 6-inch opening, insert the collar, and fold the tab against the board interior. Verify the seam is sealed with approved duct tape or mastic per SMACNA guidelines before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dip Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollar Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTab Width\u003c\/strong\u003e: 1.5 inches\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: 84ST_1-1\/2X6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283911115058,"sku":"84ST_1-1\/2X6","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277589.jpg?v=1781063052","url":"https:\/\/voomisupply.com\/products\/southwark-metal-84st_1-1-2x6-ductboard-collar-tap-6-in","provider":"Voomi Supply","version":"1.0","type":"link"}
