Constructed from hot dip galvanized steel, this fitting delivers a corrosion-resistant, airtight connection at the point of branch departure. The stick-on design allows the fitting to be attached directly to the flat surface of a rectangular main duct, eliminating the need to cut a precise collar opening before securing. HVAC installers and sheet metal fabricators use this fitting during new construction ductwork layout and in retrofit applications where branch runs must be added to existing trunk lines.\u003c\/p\u003e\n\u003cp\u003eThis top takeoff is suited for low-pressure residential and light commercial supply air distribution systems where a round branch duct — flex or rigid — must be tapped off the top face of a rectangular trunk. The round-to-rectangular transition geometry accommodates standard 8-inch round duct connections. It is appropriate for installation in attic, basement, crawlspace, and mechanical room environments where galvanized steel fabrications are specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStick-on mounting attaches directly to rectangular duct surface without pre-cut collar opening\u003c\/li\u003e\n  \u003cli\u003eAir-Tite construction minimizes air leakage at the branch connection point\u003c\/li\u003e\n  \u003cli\u003eHot dip galvanized steel provides long-term corrosion resistance in typical HVAC environments\u003c\/li\u003e\n  \u003cli\u003eRound-to-rectangular geometry transitions an 8-inch round branch from a flat rectangular trunk face\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for sheet metal duct fittings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal fitting for low-pressure residential and light commercial forced-air duct systems using rectangular trunk and 8-inch round branch configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or journeyman sheet metal worker in accordance with SMACNA duct construction standards and local mechanical code requirements. Power down the air handling unit and verify zero airflow before cutting into or attaching to any pressurized duct section. Secure the fitting to the duct surface using sheet metal screws and seal all joints with code-approved mastic or foil-backed tape per ACCA and SMACNA guidelines. Do not rely on the stick-on adhesive alone as the sole means of mechanical attachment in applications subject to vibration or positive static pressure.\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\u003eRound Opening Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Stick-On, Air-Tite, Top Takeoff, Round to Rectangular\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: AT62_8IN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283968557362,"sku":"AT62_8IN","price":32.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278205.jpg?v=1781064525","url":"https:\/\/voomisupply.com\/products\/southwark-metal-at62_8in-duct-top-takeoff-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
