Southwark Metal 27_3-1/4X10X6 Duct Boot Wall Stack

Product Description

The SOUTHWARK METAL 27_3-1/4X10X6 is a straight wall stack sheet metal duct boot used to transition from a rectangular duct opening to a round collar in forced-air HVAC distribution systems. The inlet measures 3.25 inches by 10 inches, and the outlet is 6 inches in diameter. Fabricated from hot dip galvanized steel, this boot resists corrosion in both new construction and retrofit installations. HVAC sheet metal mechanics and installers use this fitting to connect supply ductwork to wall registers in residential and light commercial applications. It is manufactured to ACCA and SMACNA standards, making it suitable for code-compliant duct system design and installation.

This wall stack boot is designed for supply-air distribution in forced-air heating and cooling systems. It is commonly installed in wall cavities where the duct transitions from a rectangular trunk or branch to a round collar feeding a sidewall register. The straight configuration is appropriate when the duct run approaches the register box in a direct, in-line path. HVAC installers use this fitting in new construction framing as well as in retrofit scenarios where existing wall stack cavities require a new boot fitting.

Key Features

• Straight wall stack configuration for direct in-line register connections
• 3.25 inch by 10 inch rectangular inlet matches standard wall stack rough openings
• 6 inch round outlet connects to standard round collar or flex duct
• Hot dip galvanized steel construction for corrosion resistance

Compatibility

Designed as an OEM-style replacement or new-construction fitting for residential and light commercial forced-air duct systems requiring a straight wall stack boot with a 3.25 inch by 10 inch rectangular inlet and a 6 inch round outlet.

Installation Notes

Installation should be performed by a qualified HVAC technician or sheet metal mechanic in accordance with SMACNA duct construction standards and local mechanical code requirements. Power down the air handling system before connecting or sealing the boot fitting. Seal all joints with listed duct mastic or UL 181-listed tape per applicable code. Do not use this fitting as a structural framing member within the wall cavity.
