Built from hot-dipped galvanized steel, this Air-Tite unit features an integrated scoop and damper, allowing technicians to balance airflow at the takeoff point without adding separate balancing hardware. The 16-inch diameter inlet and 16-inch diameter outlet make it a direct fit for larger residential and light commercial duct runs where high-volume branch supply is required. Licensed HVAC sheet metal mechanics and duct installers are the primary trade for this component.\u003c\/p\u003e\n\u003cp\u003eThis takeoff is suited for trunk-line installations in central forced-air systems, including gas furnace, heat pump, and air handler configurations where trunk duct sizes call for a 16-inch round branch connection. The built-in scoop captures moving airflow from the main trunk and directs it into the branch, improving pressure recovery and delivery efficiency compared to a flat-top collar. The integral damper provides on-site airflow adjustment during system commissioning and balancing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot-dipped galvanized steel construction resists corrosion in conditioned and unconditioned space installations\u003c\/li\u003e\n  \u003cli\u003eAir-Tite round design minimizes air leakage at the takeoff joint\u003c\/li\u003e\n  \u003cli\u003eIntegrated scoop improves static pressure recovery from the trunk into the branch\u003c\/li\u003e\n  \u003cli\u003eBuilt-in damper allows airflow balancing without additional hardware\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for duct construction and installation\u003c\/li\u003e\n  \u003cli\u003e16-inch inlet and outlet diameters suit high-volume branch supply applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal duct takeoff for use in residential and light commercial forced-air duct systems requiring a 16-inch round branch connection on standard rectangular or round trunk ductwork.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or sheet metal mechanic following SMACNA duct construction standards and local mechanical code requirements. Shut down the air handling system and de-energize the unit before cutting into existing trunk duct. Seal all joints with listed duct sealant or UL 181-rated tape per applicable code. Adjust the damper during system commissioning to achieve design airflow as specified by the ACCA Manual D duct design.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dipped Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Air-Tite, Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize A (Inlet Diameter)\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize B (Outlet Diameter)\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInclusions\u003c\/strong\u003e: Scoop, Damper\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: ATSD_16IN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284045693234,"sku":"ATSD_16IN","price":64.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278219.jpg?v=1781067096","url":"https:\/\/voomisupply.com\/products\/southwark-metal-atsd_16in-16-inch-round-duct-takeoff","provider":"Voomi Supply","version":"1.0","type":"link"}
