Measuring 30 inches by 10 inches in cross-section and 60 inches in length, this trunk duct delivers a rigid, corrosion-resistant air pathway from the air handler or furnace to branch takeoffs throughout the structure. It ships with button snaplock seams, S-cleat end connections, and drive connection hardware included. The duct body is cross-broken for additional panel stiffness, reducing flex noise and maintaining dimensional stability under static pressure. Licensed HVAC sheet metal mechanics and ductwork installers are the primary trade for this product.\u003c\/p\u003e\n\u003cp\u003eThis trunk duct section is suited for residential and light commercial forced-air systems where main trunk runs are fabricated or extended from a central air handler, furnace, or rooftop unit. The 30-by-10-inch profile accommodates high-volume supply or return trunk applications. It is fabricated to ACCA and SMACNA standards, making it compatible with duct systems designed under Manual D airflow calculations and SMACNA duct construction guidelines. Typical installation scenarios include new construction trunk-and-branch layouts and retrofit trunk extensions where additional duct footage is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot-dip galvanized steel construction resists corrosion in both conditioned and unconditioned spaces\u003c\/li\u003e\n  \u003cli\u003e60-inch section length reduces the number of joints required in long trunk runs\u003c\/li\u003e\n  \u003cli\u003eButton snaplock seam with S-cleat and drive connection hardware included for field assembly\u003c\/li\u003e\n  \u003cli\u003eCross-broken duct panels add stiffness and reduce drumming under airflow pressure\u003c\/li\u003e\n  \u003cli\u003eFabricated to ACCA and SMACNA applicable standards\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 systems built to ACCA and SMACNA ductwork standards.

Power down the air handler or furnace and verify the system is de-energized before connecting new duct sections. Joints should be secured with the included S-cleat and drive connections and sealed with UL 181-rated mastic or foil tape per local mechanical code requirements. Support hangers should be spaced per SMACNA guidelines to prevent sag and maintain alignment across the trunk run.\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\u003eCross-Section Width\u003c\/strong\u003e: 30 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross-Section Height\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 60 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeam Type\u003c\/strong\u003e: Button Snaplock\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\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_30X10X60\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284024885554,"sku":"TD_30X10X60","price":152.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277267.jpg?v=1781066420","url":"https:\/\/voomisupply.com\/products\/southwark-metal-td_30x10x60-sheet-metal-trunk-duct","provider":"Voomi Supply","version":"1.0","type":"link"}
