Fabricated from hot-dip galvanized steel, this end cap measures 16 inches by 12 inches and seals the open end of a matching trunk duct section. It prevents uncontrolled air leakage at duct termination points, maintaining system static pressure and overall airflow efficiency. Sheet metal contractors and HVAC installers fit this cap during ductwork fabrication and installation in new construction and retrofit applications.\u003c\/p\u003e\n\u003cp\u003eThis end cap is suited for residential and light commercial forced-air systems where rectangular trunk duct is used to distribute conditioned air from the air handler or furnace. It is appropriate for use in trunk-and-branch duct layouts that conform to ACCA and SMACNA standards. The 16-inch by 12-inch profile fits standard trunk duct of the same nominal dimensions and is installed at any dead-end termination in the duct system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot-dip galvanized steel construction provides corrosion resistance for long-term duct system durability\u003c\/li\u003e\n  \u003cli\u003eSized at 16 inches by 12 inches for a direct fit on matching rectangular trunk duct\u003c\/li\u003e\n  \u003cli\u003eTrunk-type configuration seals dead-end duct runs and prevents conditioned air loss\u003c\/li\u003e\n  \u003cli\u003eFabricated to ACCA and SMACNA applicable standards for sheet metal ductwork\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal component for use with standard 16-inch by 12-inch rectangular trunk duct sections in forced-air HVAC distribution systems built to ACCA and SMACNA guidelines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed sheet metal contractors or HVAC technicians. Power down the air handler or furnace and verify the system is de-energized before working on ductwork. The end cap is typically secured using sheet metal screws and sealed with UL 181-listed duct sealant or approved foil tape per SMACNA installation standards. Wear appropriate gloves when handling cut sheet metal edges.\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\u003eSize\u003c\/strong\u003e: 16 inches x 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Trunk\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: 21_16X12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283993788722,"sku":"21_16X12","price":18.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277198.jpg?v=1781065382","url":"https:\/\/voomisupply.com\/products\/southwark-metal-21_16x12-trunk-duct-end-cap-16x12","provider":"Voomi Supply","version":"1.0","type":"link"}
