Lukjan SB203107 Universal Wall Stack Boot 3.25x10

Product Description

The LUKJAN SB203107 is a universal wall stack boot designed for residential and light commercial HVAC duct systems. This fitting connects a rectangular duct run to a floor or wall register, transitioning airflow from the main trunk or branch duct to the supply outlet. It measures 3.25 inches by 10 inches at the duct opening, making it a standard-size option for common residential duct layouts. HVAC installers and sheet metal technicians use this boot during new construction or retrofit projects where a reliable, properly sized transition fitting is required.

The SB203107 wall stack boot is suited for residential forced-air heating and cooling systems. It fits wall or floor register installations where a 3.25-inch by 10-inch duct collar is required. The universal design accommodates a range of installation orientations, making it a practical choice for both new duct runs and replacement applications in existing systems.

Key Features

• 3.25-inch by 10-inch duct opening for standard residential supply runs
• Sized for common trunk-to-register transitions in forced-air systems
• Suitable for new construction and retrofit duct installations

Compatibility

Designed as an OEM-style replacement and new-installation fitting for residential forced-air HVAC duct systems requiring a 3.25-inch by 10-inch wall stack boot connection.

Installation Notes

Installation is typically performed by a licensed HVAC technician or qualified sheet metal installer. Power down the air handling unit and verify the system is de-energized before beginning ductwork modifications. Secure the boot to the duct with sheet metal screws and seal all joints with UL-listed duct sealant or approved foil tape per local mechanical code requirements. Do not compress or distort the boot opening during installation, as this will restrict airflow and affect system performance.
