The LUKJAN SB302106 is an elbow wall stack boot designed for residential and light commercial duct distribution systems. This fitting connects a wall stack duct run to a floor or wall register opening, providing the directional transition needed to terminate supply air at the point of delivery. The SB302106 measures 2.25 inches by 10 inches by 6 inches, making it suited for standard wall stack applications. HVAC installers and sheet metal mechanics use this fitting during new construction and retrofit duct work where a clean, low-profile elbow transition is required.
This elbow boot fits into wall stack duct systems, which are commonly used in residential forced-air installations where duct runs travel through interior wall cavities. The compact profile of the SB302106 allows it to terminate within standard framing dimensions. It is appropriate for supply-air termination points in single-family homes and light commercial builds using conventional forced-air heating and cooling equipment.
Designed as an OEM-style replacement and new-installation fitting for residential and light commercial wall stack duct systems using standard 2.25-inch by 10-inch wall stack duct profiles.
Installation of this fitting is typically performed by a licensed HVAC technician or journeyman sheet metal mechanic. Power down the air handling unit at the disconnect or breaker before working inside any duct system. Secure the boot to the duct run using sheet metal screws and seal all joints with UL-listed duct tape or mastic sealant per local mechanical code requirements. Verify register opening dimensions match the boot face before finalizing the installation.
