Lukjan rx1209 Round Takeoff Metal Tab Collar 9 Inch

Product Description

The LUKJAN rx1209 is a 9-inch metal tab collar designed for use in HVAC duct distribution systems. Sold under the Series T27 designation, this round takeoff fitting connects branch duct runs to rectangular plenums or main trunk lines. The tab collar design allows for tool-free or minimal-tool installation, with the stamped metal tabs folding over to secure the fitting in place without additional fasteners. Licensed HVAC technicians and sheet metal mechanics are the primary installers for this type of fitting.

This round takeoff collar is suited for residential and light commercial forced-air HVAC systems. It is used at branch-off points on supply plenums and duct trunk lines where a round branch run must be connected. The Series T27 classification indicates a standard metal tab collar configuration. Installation is typically performed during new construction duct fabrication or duct modification and replacement service work.
