Fabricated from hot dip galvanized steel, it measures 12 inches by 10 inches in cross section and runs 48 inches in length. The section ships ready for field assembly using a button snap-lock seam with S-cleat and drive connection, eliminating the need for additional hardware on the longitudinal joint. Cross breaking on the flat panels reduces drumming and increases rigidity under positive static pressure. Licensed HVAC technicians and sheet metal mechanics install this duct as part of residential or light commercial supply-air trunk runs.\u003c\/p\u003e\n\u003cp\u003eThis trunk duct section is suited for residential and light commercial forced-air systems where a 12-inch by 10-inch rectangular main or branch trunk is specified by load calculations. The 48-inch section length is standard for straight trunk runs and fits within typical joist-bay and mechanical-room layouts. The hot dip galvanized coating resists corrosion in unconditioned spaces such as attics, basements, and crawlspaces. Installation follows SMACNA and ACCA duct construction standards, making it appropriate for permitted new construction and retrofit duct work alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot dip galvanized steel construction for corrosion resistance in unconditioned spaces\u003c\/li\u003e\n  \u003cli\u003eButton snap-lock seam with S-cleat and drive connection for tool-friendly field assembly\u003c\/li\u003e\n  \u003cli\u003eCross broken flat panels reduce vibration and drumming under airflow pressure\u003c\/li\u003e\n  \u003cli\u003e12 x 10 x 48 inch dimensions suit standard residential and light commercial trunk layouts\u003c\/li\u003e\n  \u003cli\u003eMeets SMACNA and ACCA applicable standards for sheet metal duct construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal trunk duct section for residential and light commercial forced-air HVAC supply systems requiring a 12-inch by 10-inch rectangular duct profile with standard S-cleat and drive-end connections.\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 mechanic in accordance with SMACNA duct construction standards and local mechanical codes. Shut down the air-handling unit and confirm the system is de-energized before connecting to an existing trunk. S-cleat and drive connections must be fully seated and secured with sheet metal screws at all joints; seal longitudinal and transverse seams with UL 181-listed duct mastic or approved foil tape to meet energy code requirements. Support the duct at intervals consistent with SMACNA hanger and support guidelines for the installed weight and duct size.\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: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight (Size B)\u003c\/strong\u003e: 10 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_12X10X48\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284138361138,"sku":"TD_12X10X48","price":37.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277210.jpg?v=1781069543","url":"https:\/\/voomisupply.com\/products\/southwark-metal-td_12x10x48-sheet-metal-trunk-duct","provider":"Voomi Supply","version":"1.0","type":"link"}
