Measuring 30 inches by 8 inches in cross-section and 48 inches in length, this duct section handles supply air delivery in residential and light commercial installations. Construction features button snap-lock seams with S-cleat and drive connections for secure, field-ready assembly. Cross-breaking on the flat panels adds rigidity and reduces metal flexing and noise under airflow pressure. Licensed HVAC technicians and sheet metal contractors install this product as part of new construction or replacement trunk line runs.\u003c\/p\u003e\n\u003cp\u003eThis trunk duct section is suited for rectangular supply air trunk lines in forced-air heating and cooling systems. The 30-inch by 8-inch profile accommodates medium to large duct runs where airflow capacity and structural stiffness are required. The hot-dip galvanized finish provides corrosion resistance in attic, crawlspace, and basement installations. S-cleat and drive connection ends allow this section to connect directly to adjacent fittings and duct sections following standard sheet metal assembly practices compliant with ACCA and SMACNA guidelines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot-dip galvanized steel construction for corrosion resistance in varied installation environments\u003c\/li\u003e\n  \u003cli\u003eButton snap-lock seam with S-cleat and drive connection ends for fast, secure field assembly\u003c\/li\u003e\n  \u003cli\u003eCross-broken flat panels for added rigidity and reduced drumming under airflow\u003c\/li\u003e\n  \u003cli\u003e30 inches by 8 inches cross-section profile for medium to large trunk line applications\u003c\/li\u003e\n  \u003cli\u003e48-inch section length reduces the number of joints needed in a straight trunk run\u003c\/li\u003e\n  \u003cli\u003eManufactured to ACCA and SMACNA applicable standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard rectangular sheet metal trunk duct section compatible with S-cleat and drive-style duct connections used in residential and light commercial forced-air HVAC distribution systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Shut down the air handler or furnace and lock out power before modifying or extending an existing duct system. S-cleat and drive connections require standard sheet metal hand tools and should be sealed with UL 181-listed duct sealant or foil tape per local mechanical code requirements. Support hangers and spacing should follow SMACNA duct installation standards for the duct weight and run length.\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\u003eWidth (Size A)\u003c\/strong\u003e: 30 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight (Size B)\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 48 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Button Snap-Lock with S-Cleat and Drive Connection\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePanel Reinforcement\u003c\/strong\u003e: Cross Broken\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: TD_30X8X48\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283901088050,"sku":"TD_30X8X48","price":71.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277269.jpg?v=1781062780","url":"https:\/\/voomisupply.com\/products\/southwark-metal-td_30x8x48-trunk-duct-30x8x48-galvanized","provider":"Voomi Supply","version":"1.0","type":"link"}
