Value Collection 15232600 Galvanized Duct Stack 3-1/4 in Id

Product Description

The VALUE COLLECTION 15232600 is a galvanized steel duct stack fitting designed for use in residential and light commercial HVAC sheet metal duct systems. With a 3-1/4 inch inside diameter, a 60-inch height, and a 12-inch overall length, this stack fitting channels conditioned air from a main trunk line into a wall or floor cavity, directing airflow to individual supply registers. The galvanized construction provides corrosion resistance suited for typical forced-air duct installations. At 7.5 pounds, it is sized for standard residential duct stack configurations. HVAC sheet metal installers and mechanical contractors are the primary trades that handle this component.

This duct stack fitting is used in forced-air heating and cooling systems where conditioned air is distributed through wall or floor cavities to supply registers. It is most commonly installed during new construction or renovation rough-in work where a trunk-to-register transition is needed. The 3-1/4 inch ID matches common residential register boot opening dimensions, making it appropriate for standard single-slot or narrow wall register installations. Standard gage galvanized material meets typical residential mechanical specifications.

Key Features

• 3-1/4 inch inside diameter for standard residential duct stack applications
• 60-inch height provides full-depth wall cavity coverage in standard stud bays
• 12-inch overall length for trunk-to-register transitions
• Galvanized steel construction resists corrosion in typical forced-air duct environments
• Standard gage material compatible with common sheet metal duct system specifications
• Single-unit packaging allows purchase of individual fittings as needed

Compatibility

Designed as an OEM-style replacement or new-installation fitting for residential forced-air duct systems requiring a 3-1/4 inch ID galvanized stack fitting.

Installation Notes

Installation is performed by licensed HVAC technicians or sheet metal contractors following applicable mechanical codes. Secure the stack fitting to the trunk line using sheet metal screws and seal all joints with UL-listed foil tape or mastic sealant to prevent air leakage. Ensure the wall or floor cavity is clear of obstructions before inserting the stack. Always verify duct system static pressure and airflow requirements before selecting stack fitting dimensions.
