Southwark Metal TD_24X8X48 Sheet Metal Trunk Duct 24x8x48

Product Description

The SOUTHWARK METAL TD_24X8X48 is a hot-dip galvanized steel sheet metal trunk duct measuring 24 inches by 8 inches by 48 inches. It is designed for supply and return air distribution in forced-air HVAC systems. The duct section features a button snap-lock seam with S-cleat and drive connection ends for secure, field-ready assembly. Cross-breaking on the flat panels adds rigidity and reduces oil-canning. Licensed HVAC technicians and sheet metal installers work with this component during new construction and retrofit ducting projects where a rigid rectangular trunk run is required.

This trunk duct section is suited for residential and light commercial forced-air systems where a 24 x 8 inch rectangular main or branch trunk run is specified. The 48-inch length allows for straightforward layout planning along a joist bay or furring chase. The S-cleat and drive connection end configuration integrates with standard rectangular duct fittings, transitions, and boots already on the job. It is fabricated to meet ACCA and SMACNA duct construction standards, making it appropriate for projects subject to those specifications.

Key Features

• Hot-dip galvanized steel construction for corrosion resistance in conditioned and unconditioned spaces
• Button snap-lock longitudinal seam for fast, secure panel closure without additional fasteners
• S-cleat and drive connection ends for tool-accessible field assembly with mating duct sections and fittings
• Cross-broken flat panels add structural rigidity and minimize drumming under airflow pressure
• Fabricated to ACCA and SMACNA duct construction standards
• 48-inch section length simplifies layout and reduces the number of joints in a straight run

Compatibility

Designed as an OEM-style rectangular trunk duct section for use in standard 24 x 8 inch forced-air HVAC duct systems using S-cleat and drive connection assembly methods.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal installer in accordance with SMACNA duct construction guidelines and applicable local mechanical codes. Shut down the air handling unit and lock out the system before connecting or modifying existing duct runs. Use proper drive cleats, S-cleats, and duct hangers at recommended intervals to support the trunk run securely. Seal all transverse joints and seams with listed duct sealant or mastic per local energy code requirements.
