The SNAPPY 200-324 is a galvanized steel wallstack duct section measuring 3.25 inches wide by 12 inches tall by 48 inches long. Wallstack ducts are used in residential forced-air HVAC systems to route supply air through wall cavities, typically between floors or within interior wall chases. The galvanized steel construction resists corrosion and holds its shape under normal duct pressures. HVAC sheet metal installers use this fitting as part of a trunk-and-branch or perimeter supply system during new construction or renovation work.
Wallstack sections like the 200-324 are a standard component in residential low-profile supply duct runs where a flat rectangular profile is required to fit inside a framed wall cavity. The 3.25 by 12 inch cross-section matches common residential register boot and trunk sizing, making it well-suited for first-floor and multi-story supply runs. This fitting is typically installed during rough-in framing before drywall is hung.
Designed as an OEM-style supply duct section for residential forced-air HVAC systems using 3.25 inch by 12 inch rectangular duct configurations.
Installation should be performed by a licensed HVAC technician or sheet metal installer following local mechanical codes and SMACNA duct construction standards. Power down the air handling system before working on any connected ductwork. Seal all longitudinal seams and transverse joints with listed duct sealant or approved metal tape per code requirements. Avoid compressing or crimping the duct section during installation, as deformation reduces airflow performance.
