It measures 26 inches by 8 inches in cross-section and 48 inches in length. The duct ships with a button snap-lock seam and connects to adjacent sections using S-cleat and drive connections on each end. Cross breaking is applied to the flat panels to reduce oil-canning and maintain panel rigidity under airflow pressure. This trunk duct is installed by sheet metal mechanics and HVAC technicians in low-pressure forced-air distribution systems.\u003c\/p\u003e\n\u003cp\u003eThis duct section is suited for residential and light commercial HVAC trunk-and-branch layouts where a 26-by-8-inch rectangular duct is specified. The 48-inch length fits standard stud-bay and joist-bay runs and works within systems designed to ACCA Manual D airflow sizing guidelines and SMACNA duct construction standards. Installers use it as a main trunk run off an air handler or furnace, transitioning to smaller branch takeoffs along the system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot dip galvanized steel construction resists corrosion in attic, crawlspace, and basement installations\u003c\/li\u003e\n  \u003cli\u003eButton snap-lock seam secures the longitudinal joint without additional fasteners\u003c\/li\u003e\n  \u003cli\u003eS-cleat and drive connection system allows fast field assembly and sealing at duct joints\u003c\/li\u003e\n  \u003cli\u003eCross-broken flat panels reduce vibration and panel flex under operating static pressure\u003c\/li\u003e\n  \u003cli\u003eConforms to ACCA and SMACNA applicable standards for low-pressure rectangular duct fabrication\u003c\/li\u003e\n  \u003cli\u003e48-inch section length reduces the number of joints required on longer trunk runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style rectangular trunk duct section for use in low-pressure residential and light commercial forced-air HVAC distribution systems built to ACCA and SMACNA standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSheet metal trunk duct is installed by licensed HVAC technicians or journeyman sheet metal mechanics. Power down the air handler or furnace and verify the system is de-energized before connecting new duct sections. All longitudinal seams and transverse joints should be sealed with UL 181-listed mastic or foil tape per local mechanical code requirements. Support hangers should be spaced per SMACNA guidelines to prevent sag and maintain proper airflow geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth (Size A)\u003c\/strong\u003e: 26 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\u003eMaterial\u003c\/strong\u003e: Hot Dip Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeam Type\u003c\/strong\u003e: Button Snap-Lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: S-Cleat and Drive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePanel Treatment\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_26X8X48\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283962102066,"sku":"TD_26X8X48","price":72.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277279.jpg?v=1781064319","url":"https:\/\/voomisupply.com\/products\/southwark-metal-td_26x8x48-sheet-metal-trunk-duct","provider":"Voomi Supply","version":"1.0","type":"link"}
