It measures 16 inches by 14 inches in cross-section and runs 48 inches in length, making it a standard full-section piece for main supply trunk lines. The cross-broken panel construction adds rigidity and reduces drumming under pressure. Connection is handled by a button snap-lock seam with S-cleat and drive connection ends, allowing fast, secure field assembly. Licensed HVAC sheet metal mechanics and HVAC installers work with this component during new construction and system retrofit projects.\u003c\/p\u003e\n\u003cp\u003eThis trunk duct section is suited for residential and light commercial forced-air supply systems where a rectangular main trunk is required. It integrates into standard rectangular duct systems following SMACNA and ACCA duct construction guidelines. The 16-by-14-inch profile accommodates a range of system airflow designs and is commonly installed in attic, basement, or crawlspace applications where a full-length trunk run is being assembled or extended.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot-dip galvanized steel construction resists corrosion in humid and unconditioned spaces\u003c\/li\u003e\n  \u003cli\u003eCross-broken panel adds structural stiffness and reduces noise and flex under static pressure\u003c\/li\u003e\n  \u003cli\u003eButton snap-lock seam provides a tight, secure longitudinal joint without additional fasteners\u003c\/li\u003e\n  \u003cli\u003eS-cleat and drive connection ends allow fast field joining to adjacent duct sections or fittings\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for duct construction\u003c\/li\u003e\n  \u003cli\u003eFull 48-inch section length reduces the number of joints in long trunk runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-construction trunk duct section for rectangular sheet metal supply air systems requiring a 16-inch by 14-inch cross-section with standard S-cleat and drive connection ends.\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 mechanic in accordance with SMACNA duct construction standards and local mechanical codes. Power down the air handling unit and isolate the system before making any duct connections or modifications. Seal all joints with UL 181-listed duct sealant or approved mastic after mechanical connection to prevent air leakage. Support spacing and hanger requirements should follow 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: 16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight (Size B)\u003c\/strong\u003e: 14 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\u003eConstruction Feature\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_16X14X48\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283916194098,"sku":"TD_16X14X48","price":82.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277253.jpg?v=1781063176","url":"https:\/\/voomisupply.com\/products\/southwark-metal-td_16x14x48-sheet-metal-trunk-duct","provider":"Voomi Supply","version":"1.0","type":"link"}
