Fabricated from hot dip galvanized steel, this cap provides durable, corrosion-resistant closure that holds up in attic, crawlspace, and mechanical room environments. Sized at 12 inches by 10 inches, it fits standard trunk duct terminations of that dimension. HVAC sheet metal contractors and duct fabricators install this cap as part of a complete, sealed duct system to prevent air bypass and maintain system static pressure.\u003c\/p\u003e\n\u003cp\u003eThis end cap is used in residential and light commercial forced-air systems wherever a rectangular trunk duct requires termination. It is appropriate for new construction duct installations and retrofit or repair work on existing sheet metal duct systems. The galvanized steel construction aligns with SMACNA duct construction standards and ACCA design guidelines, making it a compliant choice on projects where those standards are specified or 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, basement, and crawlspace installations\u003c\/li\u003e\n  \u003cli\u003e12-inch by 10-inch size fits standard rectangular trunk duct terminations\u003c\/li\u003e\n  \u003cli\u003eTrunk-type end cap design closes duct ends to prevent unintended air bypass\u003c\/li\u003e\n  \u003cli\u003eMeets applicable ACCA and SMACNA standards for sheet metal duct construction\u003c\/li\u003e\n  \u003cli\u003eSuitable for new construction and retrofit duct system work\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 12-inch by 10-inch rectangular trunk duct systems built to SMACNA and ACCA specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC contractor or sheet metal mechanic. Shut down and de-energize the air handling equipment before beginning any duct work. The cap should be secured and sealed in accordance with SMACNA duct construction standards, using appropriate fasteners and duct sealant or mastic to maintain system airtightness.
