It is used to close off the open end of a rectangular trunk duct run in forced-air HVAC distribution systems. The galvanized steel construction provides corrosion resistance suitable for both conditioned and unconditioned spaces. This fitting meets ACCA and SMACNA fabrication standards, making it appropriate for commercial and residential duct systems where code-compliant sheet metal work is required. HVAC sheet metal contractors and duct installers are the primary trade installing this type of fitting.\u003c\/p\u003e\n\u003cp\u003eThis end cap is designed for trunk-style rectangular ductwork and is sized to cap a 30-inch by 10-inch duct opening. It is typically installed at the terminal end of a main supply or return trunk where no further duct extension is needed. Suitable for new construction and retrofit applications in light commercial and residential forced-air systems. The hot dip galvanized finish meets standard shop-fabricated duct requirements per SMACNA guidelines.\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 applications\u003c\/li\u003e\n  \u003cli\u003eSized to fit 30-inch x 10-inch rectangular trunk duct openings\u003c\/li\u003e\n  \u003cli\u003eTrunk-type end cap closes off terminal duct ends cleanly and securely\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for sheet metal duct fittings\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard rectangular trunk duct systems in forced-air HVAC installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard sheet metal fitting for rectangular trunk ductwork with a 30-inch x 10-inch opening, conforming to ACCA and SMACNA fabrication standards for forced-air HVAC distribution systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed sheet metal contractor or qualified HVAC technician.
