Lukjan rb306107 Elbow Boot 6x10x7 Inch Duct Fitting

Product Description

The LUKJAN rb306107 is a 90-degree elbow boot designed to transition from a round duct to a rectangular outlet in residential and light commercial HVAC duct systems. Fabricated from galvanized steel, this fitting measures 6 x 10 x 7 inches and delivers a secure, low-turbulence connection between supply trunk lines and floor, ceiling, or wall register openings. Its formed seams and rigid construction help minimize air leakage at the transition point, supporting overall system efficiency. HVAC technicians use this boot as a standard component in forced-air duct installations.

This elbow boot is suited for residential forced-air heating and cooling systems and light commercial applications where a round-to-rectangular duct transition is required. It installs at supply air outlets, connecting the round branch duct to the rectangular register or grille opening. The 6-inch round inlet and 10 x 7-inch rectangular outlet dimensions make it a common fit for standard residential supply runs serving floor boots, ceiling drops, or sidewall registers.

Key Features

• 90-degree elbow configuration transitions round duct to rectangular outlet
• Galvanized steel construction resists corrosion in conditioned air environments
• 6 x 10 x 7 inch sizing fits standard residential supply duct runs
• Rigid formed body minimizes air leakage at the transition point
• Suitable for both residential and light commercial HVAC duct systems

Compatibility

Designed as an OEM-style replacement or new-installation fitting for residential and light commercial forced-air HVAC duct systems requiring a round-to-rectangular elbow boot transition.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal contractor. Power down the air handler or furnace and verify the system is off before beginning ductwork modifications. Secure the boot with sheet metal screws and seal all joints with UL 181-rated mastic or foil tape to meet local mechanical code requirements. Verify register opening dimensions match the rectangular outlet before installation to ensure a flush, airtight fit.
