Compatible with both 1-inch and 1.5-inch ductboard, this collar maintains proper airflow routing and system integrity at connection points. It is a standard component in ductboard fabrication and is installed by HVAC technicians working on residential and commercial forced-air systems. The collar supports clean, stable connections that reduce air leakage and help maintain system efficiency.\u003c\/p\u003e\n\u003cp\u003eThis collar is used in ductboard takeoff and fitting applications where a round duct must connect to a flat ductboard panel. It fits both 1-inch and 1.5-inch ductboard thicknesses, making it versatile across common ductboard systems used in light commercial and residential HVAC installations. Typical applications include supply air distribution in forced-air systems where ductboard is used as the primary duct material.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-inch diameter collar sized for standard round duct connections\u003c\/li\u003e\n  \u003cli\u003e6-inch collar length provides sufficient engagement for a secure fit\u003c\/li\u003e\n  \u003cli\u003eCompatible with both 1-inch and 1.5-inch ductboard panels\u003c\/li\u003e\n  \u003cli\u003eDesigned for ductboard takeoff and fitting applications in HVAC systems\u003c\/li\u003e\n  \u003cli\u003eSupports consistent airflow routing and reduced leakage at transition points\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1-inch and 1.5-inch ductboard panels in residential and light commercial HVAC ductboard installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians. Power down the air handling system before beginning any ductwork modifications.
