Fabricated from hot dip galvanized steel, it provides corrosion resistance suited to the temperature and humidity conditions found inside forced-air duct systems. This fitting is installed by HVAC sheet metal mechanics and duct installers during new construction or retrofit work where an open duct terminus must be sealed to maintain system static pressure and prevent air bypass.\u003c\/p\u003e\n\u003cp\u003eThis end cap is used in residential and light commercial forced-air HVAC systems where rectangular trunk duct runs are terminated at a wall, floor, or mechanical room boundary. It fits 14-inch by 12-inch trunk duct openings and is appropriate for supply or return trunk applications. Installation typically follows SMACNA and ACCA duct construction standards, making it suitable for projects where those standards are specified by design or local code.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot dip galvanized steel construction for corrosion resistance in HVAC duct environments\u003c\/li\u003e\n  \u003cli\u003eSized for 14-inch by 12-inch rectangular trunk duct openings\u003c\/li\u003e\n  \u003cli\u003eTrunk-type end cap profile for a flush, secure closure at duct terminations\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for duct fittings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal fitting for use with standard 14-inch by 12-inch rectangular trunk duct sections in forced-air HVAC systems built to SMACNA or ACCA duct construction guidelines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified sheet metal mechanics. Power down the air handling unit and confirm the system is de-energized before working inside the duct system. The end cap is typically secured to the duct opening using sheet metal screws and sealed with UL 181-rated duct sealant or mastic to prevent air leakage. Follow SMACNA duct construction standards and applicable local mechanical codes for fastener spacing and sealing requirements.\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: 14 inches x 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Trunk End Cap\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_14X12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283994116402,"sku":"21_14X12","price":19.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277218.jpg?v=1781065393","url":"https:\/\/voomisupply.com\/products\/southwark-metal-21_14x12-trunk-duct-end-cap-14x12","provider":"Voomi Supply","version":"1.0","type":"link"}
