Measuring 8 inches by 8 inches in cross-section and 48 inches in length, this duct section connects into trunk-and-branch air distribution layouts. The button snap-lock seam construction pairs with an S-cleat and drive connection system for secure, field-ready assembly. Cross-breaking on the flat panels adds rigidity and reduces oil-canning. Licensed HVAC contractors and sheet metal mechanics install this type of duct section during new construction and retrofit air distribution projects.\u003c\/p\u003e\n\u003cp\u003eThis trunk duct section is suited for residential and light commercial forced-air systems where rectangular galvanized ductwork is specified. It fits into standard trunk-and-branch layouts as a straight run section, typically installed in attics, crawlspaces, basements, or mechanical rooms. The 8 x 8 inch profile accommodates low-clearance installations. Fabricated to ACCA and SMACNA standards, this duct section meets the quality and dimensional requirements used by inspectors and design engineers on permitted HVAC projects.\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 environments\u003c\/li\u003e\n  \u003cli\u003eButton snap-lock seam provides fast, secure longitudinal closure without additional fasteners\u003c\/li\u003e\n  \u003cli\u003eS-cleat and drive connection ends allow quick field assembly to adjacent duct sections or fittings\u003c\/li\u003e\n  \u003cli\u003eCross-broken flat panels add structural rigidity and reduce panel flex noise during system operation\u003c\/li\u003e\n  \u003cli\u003eFabricated to ACCA and SMACNA applicable standards for use on permitted installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-construction component for residential and light commercial rectangular trunk duct systems using standard S-cleat and drive connection fittings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC contractor or journeyman sheet metal mechanic in accordance with SMACNA duct construction standards and local mechanical codes. Power down the air handling unit and confirm the system is de-energized before connecting or modifying duct runs. Use appropriate S-cleats, drive cleats, and sheet metal screws to secure joints, and seal all longitudinal seams and end connections with UL 181-listed mastic or approved foil tape per local code requirements. Support hangers should be spaced per SMACNA guidelines for the duct size and weight.\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: 8 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\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 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_8X8X48\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283930513714,"sku":"TD_8X8X48","price":26.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277270.jpg?v=1781063484","url":"https:\/\/voomisupply.com\/products\/southwark-metal-td_8x8x48-sheet-metal-trunk-duct-8x8x48","provider":"Voomi Supply","version":"1.0","type":"link"}
