Fabricated from hot dip galvanized steel, this collar provides a durable, corrosion-resistant connection point where branch ducts or fittings originate from a main trunk line. Measuring 26 inches by 12 inches, it is sized for medium-to-large trunk duct runs and is built to meet ACCA and SMACNA standards for sheet metal ductwork fabrication and performance.\u003c\/p\u003e\n\u003cp\u003eThis starting collar is used at the beginning of a trunk duct run, typically installed directly off an air handler, furnace plenum, or main supply trunk. It is suited for forced-air systems in residential new construction, renovation, and light commercial applications. HVAC sheet metal mechanics and duct installers use this fitting to establish a clean, square takeoff point from the trunk, ensuring proper airflow distribution at the start of the duct system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot dip galvanized steel construction resists corrosion in both conditioned and unconditioned spaces\u003c\/li\u003e\n  \u003cli\u003eStraight body pattern provides a clean, direct starting connection on trunk duct systems\u003c\/li\u003e\n  \u003cli\u003e26 inch by 12 inch size accommodates medium-to-large supply trunk runs\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for sheet metal ductwork\u003c\/li\u003e\n  \u003cli\u003eStarting collar type establishes the origin point of a trunk duct run\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 in forced-air HVAC trunk duct systems built to ACCA and SMACNA specifications, fitting trunk openings of 26 inches by 12 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified sheet metal mechanic.
