Fabricated from hot-dip galvanized steel, this section measures 20 inches wide by 14 inches tall by 48 inches long. It connects using a button snap-lock seam with S-cleat and drive connection ends, allowing fast, secure field assembly. The cross-broken panels add rigidity and reduce drumming under airflow. Licensed HVAC sheet metal mechanics and 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 installations where a main supply or return duct run requires a full 48-inch rectangular section. The 20-by-14-inch cross section supports high-volume airflow distribution from an air handler or furnace. It is fabricated to ACCA and SMACNA standards, making it appropriate for jobs where code-compliant ductwork documentation is required.\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 with S-cleat and drive connection ends for fast, tool-minimal field assembly\u003c\/li\u003e\n  \u003cli\u003eCross-broken panels increase structural rigidity and reduce vibration and drumming under system pressure\u003c\/li\u003e\n  \u003cli\u003eFull 48-inch section length reduces the number of joints in long trunk runs\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 rectangular trunk duct section compatible with standard S-cleat and drive connection ductwork assemblies in forced-air residential and light commercial HVAC systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified HVAC technician or licensed sheet metal mechanic following SMACNA duct construction standards and applicable local mechanical codes. Power down the air handling equipment before making duct connections. Secure all S-cleat and drive connections fully before sealing joints with approved mastic or foil tape per energy code requirements. Support the duct section at intervals consistent with SMACNA hanger and support guidelines for the duct weight and 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: 20 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\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_20X14X48\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283980878130,"sku":"TD_20X14X48","price":102.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277241.jpg?v=1781064943","url":"https:\/\/voomisupply.com\/products\/southwark-metal-td_20x14x48-trunk-duct-20x14x48","provider":"Voomi Supply","version":"1.0","type":"link"}
