Lukjan dx7618 Ductboard Collar 18x6 Inch

Product Description

The LUKJAN dx7618 is an 18-inch ductboard collar with a 6-inch length, designed to create a secure and precise transition between ductboard panels and round duct runs. 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.

This 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.
