Southwark Metal 24_3-1/4X12X7 Duct Wall Stack Elbow Boot

Product Description

The SOUTHWARK METAL 24_3-1/4X12X7 is a hot dip galvanized steel sheet metal duct boot designed for wall stack applications in residential forced-air HVAC systems. This 90-degree elbow boot transitions airflow from a vertical wall cavity to a horizontal register opening, making it a standard component in new construction and retrofit duct installations. The rectangular inlet measures 3.25 inches by 12 inches, and the outlet is 7 inches in diameter. HVAC sheet metal mechanics and duct installers work with this fitting when building or replacing supply-side ductwork in interior wall stacks. Construction meets ACCA and SMACNA standards.

This boot is used in residential and light commercial forced-air supply duct systems where a wall stack feeds a floor or baseboard register. The 90-degree elbow geometry allows the duct run to turn from vertical to horizontal at the termination point. Typical installations include interior wall cavities in single-family homes and multi-unit residential construction where space-saving flat oval or rectangular duct profiles are required at the supply outlet.
