Snappy 200-322 Galvanized Wallstack Duct 3.25x12x24 in

Product Description

The SNAPPY 200-322 is a galvanized steel wallstack duct fitting measuring 3.25 inches x 12 inches x 24 inches. Wallstacks are used to connect rectangular duct runs to wall registers in residential forced-air HVAC systems, providing the transition point between the supply trunk or branch duct and the wall cavity. This fitting is fabricated from galvanized steel for corrosion resistance and long service life. HVAC installers and sheet metal contractors work with this component during new construction and duct replacement projects.

This wallstack is suited for residential forced-air heating and cooling applications where a slim rectangular duct profile is required. The 3.25 inch x 12 inch cross-section fits standard wall cavities and pairs with matching rectangular supply registers. It is a common fitting in low-profile duct systems where space between floor joists or wall studs is limited.

Key Features

• Galvanized steel construction for corrosion resistance in unconditioned spaces
• Standard 3.25 inch x 12 inch x 24 inch dimensions fit common wall cavity installations
• 24-inch length suits typical stud-bay and joist-bay duct runs
• Designed for use with rectangular supply registers and branch duct connections

Compatibility

Designed as an OEM-style replacement and new-installation fitting for residential forced-air supply duct systems using 3.25 inch x 12 inch rectangular duct configurations.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal contractors. Shut down the air handling unit and confirm the system is de-energized before modifying any duct section. Secure all joints with sheet metal screws and seal with UL 181-listed mastic or foil tape per local mechanical code requirements. Verify fitting orientation and register alignment before final fastening.
