A start collar serves as the fitting that connects a branch duct takeoff to the main trunk line, allowing conditioned air to be directed from the plenum or main duct into a branch run. This fitting measures 3.25 inches by 10 inches, matching a standard rectangular duct size commonly found in residential and light commercial forced-air HVAC installations. Installation is performed by licensed HVAC technicians or sheet metal mechanics during new construction or duct retrofit work.\u003c\/p\u003e\u003cp\u003eThis start collar is suited for rectangular duct branch connections in forced-air heating and cooling systems. It is typically installed where a branch duct originates from a main trunk or plenum box. The 3.25-inch by 10-inch profile corresponds to a common duct size used in residential supply air distribution. HVAC sheet metal contractors and duct installers will find this fitting appropriate for standard low-pressure supply or return air branch applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3.25 inches by 10 inches rectangular profile fits standard duct sizing\u003c\/li\u003e\n\u003cli\u003eStart collar design provides a clean, secure branch connection point on trunk ducts or plenums\u003c\/li\u003e\n\u003cli\u003eDesigned for use in low-pressure forced-air HVAC duct systems\u003c\/li\u003e\n\u003cli\u003eCompatible with standard rectangular sheet metal ductwork fabrication methods\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting for standard 3.25-inch by 10-inch rectangular duct branch connections in residential and light commercial forced-air HVAC systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified HVAC technician or sheet metal mechanic. Shut down the air handling unit and confirm the system is de-energized before cutting into existing ductwork.
