Constructed from hot dip galvanized steel, this collar provides a corrosion-resistant transition point at the start of a ductboard run. The 2 inch tab secures the fitting flush against the ductboard face, creating a tight, low-leakage connection. At 6 inches in size, it fits standard residential and light commercial duct layouts. HVAC installers and sheet metal contractors use this fitting during new construction and duct retrofit work where ductboard is the primary distribution material.\u003c\/p\u003e\n\u003cp\u003eThis collar start is intended for use in residential and light commercial forced-air HVAC systems that incorporate rigid fiberglass ductboard. It is installed at the origin of a ductboard branch or trunk, where the duct transitions away from a metal plenum, air handler cabinet, or trunk line. The 2 inch tab design locks the fitting to the ductboard face and reduces air bypass at the connection point. Fabrication and installation should conform to ACCA and SMACNA standards for ductboard systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot dip galvanized steel construction resists corrosion in humid air stream environments\u003c\/li\u003e\n  \u003cli\u003e2 inch tab secures the collar to the ductboard face for a tight, low-leakage fit\u003c\/li\u003e\n  \u003cli\u003e6 inch size suits common residential and light commercial duct branch applications\u003c\/li\u003e\n  \u003cli\u003eDesigned and fabricated to ACCA and SMACNA applicable standards\u003c\/li\u003e\n  \u003cli\u003eProvides a clean sheet metal to ductboard transition at system start points\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style ductboard collar start fitting for use with 6 inch rigid fiberglass ductboard systems in residential and light commercial forced-air HVAC installations built to ACCA and SMACNA standards.\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.
