Lukjan TA0907 Round Saddle Collar 7 Inch

Product Description

The LUKJAN TA0907 is a 7-inch stick-on round saddle collar designed for duct branch takeoff connections in HVAC sheet metal systems. The adhesive mounting surface eliminates the need for sheet metal screws during initial positioning, speeding up layout and rough-in work on trunk-and-branch duct systems. This collar is installed by HVAC sheet metal technicians and duct fabricators working on residential and light commercial air distribution systems.

The TA0907 is suited for round duct branch connections off rectangular or oval main trunk lines. The saddle collar format allows a branch duct to tap off a main duct run at a consistent, sealed interface. It is a standard component in forced-air system duct fabrication and retrofit applications where a clean, round takeoff is required without field-cutting custom fittings.

Key Features

• 7-inch round opening for standard branch duct connections
• Stick-on adhesive backing speeds positioning during installation
• Saddle collar design provides a consistent sealed interface at the trunk duct
• Compatible with standard round flex and rigid duct branch connections

Compatibility

Designed as an OEM-style replacement and new-installation fitting for residential and light commercial forced-air duct systems requiring a 7-inch round saddle takeoff collar.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal workers. Shut down and de-energize the air handling system before cutting into or modifying any duct section. Ensure the trunk duct surface is clean and free of dust or grease before applying the adhesive backing for a proper seal. Duct connections should be sealed per local mechanical code requirements, referencing SMACNA standards where applicable.
