Southwark Metal WS12_3-1/4X10-6X10 Duct Stack Head

Product Description

The SOUTHWARK METAL WS12_3-1/4X10-6X10 is a horizontal sheet metal duct stack head designed to transition airflow from a vertical wall stack into a horizontal supply boot or register opening. Fabricated from hot dip galvanized steel, it provides corrosion resistance suited for residential and light commercial HVAC duct systems. The fitting measures 3.25 inches by 10 inches at the stack inlet and 6 inches by 10 inches at the outlet face, making it a standard-profile component for floor-to-wall duct transitions. HVAC sheet metal contractors and duct installers use this type of fitting during new construction and duct retrofit work.

This stack head is intended for horizontal installation in forced-air heating and cooling systems where a wall cavity stack feeds a floor register or baseboard supply outlet. It suits residential construction applications where space constraints call for a compact duct transition. The horizontal orientation allows the fitting to redirect conditioned air from a vertical stud-bay stack to a horizontal register opening at floor level, a common configuration in gas furnace and air handler distribution systems built to ACCA Manual D layout standards.

Key Features

• Hot dip galvanized steel construction resists corrosion in humid duct environments
• Horizontal orientation for wall-stack-to-floor-register transitions
• 3.25 x 10 inch stack inlet by 6 x 10 inch outlet face dimensions
• Meets ACCA and SMACNA applicable standards for sheet metal ductwork fabrication
• Standard profile fits typical residential stud-bay duct stack configurations

Compatibility

Designed as an OEM-style sheet metal duct fitting for residential and light commercial forced-air duct systems built to ACCA and SMACNA standards. Compatible with standard 3.25 x 10 inch wall stack duct systems.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor in accordance with SMACNA duct construction standards and local mechanical codes. Shut down the air handler or furnace and confirm the system is de-energized before beginning duct work. Secure the stack head to the wall stack and boot using sheet metal screws and approved duct sealant or mastic to prevent air leakage at all joints. Do not substitute this fitting in applications outside its rated dimensional profile without verifying airflow capacity against ACCA Manual D calculations.
