Lukjan rb104105 Duct Boot End 4x10x6 in 30 Gauge Galvanized

Product Description

The LUKJAN rb104105 is a galvanized steel duct boot end fitting designed for use in residential forced-air HVAC distribution systems. Constructed from 30-gauge hot-dipped galvanized steel, this boot end connects supply ductwork to a floor, wall, or ceiling register opening, directing conditioned air from the air handler into the living space. The fitting measures 4 inches by 10 inches by 6 inches and is hand-crafted to minimize noise and friction loss while maintaining airflow integrity. Licensed HVAC technicians and sheet metal installers rely on fittings like this for new construction and retrofit duct runs.

This boot end is suited for residential forced-air systems where supply air must transition from rectangular duct to a register opening. It is manufactured true to gauge and built in accordance with ACCA and SMACNA recommendations, making it appropriate for standard residential duct installations. The galvanized construction provides corrosion resistance, which is especially important in crawl space, basement, and slab installations where moisture exposure is common. A damper is included, allowing airflow adjustment at the boot location.

Key Features

• 30-gauge hot-dipped galvanized steel construction for rust resistance and durability

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal mechanic. Power down the air handler and close the system dampers before cutting into existing ductwork. Secure the boot end with sheet metal screws and seal all joints with UL-listed foil tape or mastic sealant to prevent air leakage. Follow local mechanical codes and SMACNA duct construction standards for proper support and fastening requirements.
