Lukjan RB306108 90 Degree Angle Boot 6x10 to 8

Product Description

The LUKJAN RB306108 is a 90-degree angle boot duct fitting designed to transition airflow from a 6x10 inch rectangular duct to an 8-inch round collar. This fitting is used to connect supply duct runs to register openings or round branch takeoffs where a right-angle turn is required. Fabricated as a sheet metal boot, it allows installers to route conditioned air from a main trunk or branch duct into a floor, wall, or ceiling register box. HVAC sheet metal mechanics and residential installers use this fitting during new construction and retrofit duct system work.

The RB306108 angle boot is suited for residential and light commercial forced-air systems where supply ductwork must turn 90 degrees to meet a register opening. It fits inline with standard rectangular supply trunk duct and terminates at an 8-inch round collar, making it compatible with common round-to-register transition assemblies. This fitting is typically installed in floor or sidewall applications where the duct must change direction before reaching the diffuser or grille location.

Key Features

• 90-degree angle configuration routes duct runs into floor, wall, or ceiling registers
• 6x10 inch rectangular inlet transitions to 8-inch round outlet collar
• Sheet metal construction suitable for residential forced-air supply duct systems

Compatibility

Designed as an OEM-style replacement and new-installation fitting for residential and light commercial forced-air HVAC supply duct systems requiring a 6x10 inch rectangular to 8-inch round, 90-degree angle transition.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal mechanics. Shut down the air handling unit and confirm the system is de-energized before cutting into existing ductwork or making connections. Secure all seams with sheet metal screws and seal joints with UL-listed foil tape or mastic sealant per local mechanical code requirements. Do not exceed the pressure rating of connected duct components.
