Southwark Metal 24R_4X12X8 Sheet Metal Pipe Boot Elbow

Product Description

The SOUTHWARK METAL 24R_4X12X8 is a hot-dip galvanized steel pipe boot elbow designed to transition ductwork from a round pipe to a rectangular register opening. Built as a 90-degree elbow, it connects an 8-inch diameter round duct to a 4-inch by 12-inch rectangular register face. This fitting is used in residential and light commercial forced-air HVAC systems to terminate supply or return duct runs at floor, wall, or ceiling register locations. HVAC sheet metal installers and duct fabricators are the primary tradespeople who work with this fitting. It meets ACCA and SMACNA standards for sheet metal duct construction.

This pipe boot elbow is suited for new construction and retrofit applications where a round duct branch must terminate at a standard 4-inch by 12-inch register. It is commonly installed at floor or sidewall register locations in residential forced-air systems. The 90-degree geometry allows the duct run to change direction cleanly at the register transition point, making it a practical choice for tight joist-bay or stud-bay installations where straight boot clearance is limited.

Key Features

• Hot-dip galvanized steel construction resists corrosion in humid duct environments
• 90-degree elbow geometry transitions round pipe to rectangular register face in a single fitting
• Rectangular opening sized at 4 inches by 12 inches for standard register compatibility
• Round collar sized at 8 inches diameter for direct connection to 8-inch round duct
• Manufactured to ACCA and SMACNA standards for sheet metal duct fabrication

Compatibility

Designed as an OEM-style sheet metal fitting for use with 8-inch round supply or return duct systems terminating at a standard 4-inch by 12-inch register in residential or light commercial forced-air HVAC applications.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal duct installers. Power down the air handling system before making duct connections. Secure the boot to the duct with sheet metal screws and seal all joints with UL 181-listed duct mastic or foil tape per SMACNA guidelines. Verify register rough-in dimensions before cutting floor or wall openings to confirm fit.
