Southwark Metal TD_24X10X48 Sheet Metal Trunk Duct 24x10x48

Product Description

The SOUTHWARK METAL TD_24X10X48 is a hot-dip galvanized steel sheet metal trunk duct section measuring 24 inches wide by 10 inches tall by 48 inches long. It is used in forced-air HVAC distribution systems to convey conditioned supply air from the air handler or furnace to branch takeoffs throughout a structure. The section features a button snap-lock seam with S-cleat and drive connection for secure field assembly and cross-breaking on the flat panels to add rigidity and reduce oil-canning. Licensed HVAC sheet metal mechanics and ductwork installers are the primary trade for this component.

This trunk duct section is suited for residential and light commercial forced-air installations where a rectangular galvanized main trunk is required. It is commonly installed in attic, crawl space, basement, and mechanical room runs. The 48-inch section length allows efficient layout of long main trunk lines with fewer joints. The S-cleat and drive connection system is a standard field-assembly method compatible with typical sheet metal duct assembly workflows on new construction and retrofit projects.

Key Features

• Hot-dip galvanized steel construction for corrosion resistance in exposed or semi-conditioned spaces
• Button snap-lock seam provides a secure longitudinal closure without additional fasteners
• S-cleat and drive connection enables standard end-to-end field joining of duct sections
• Cross-broken flat panels improve structural rigidity and reduce panel flex and noise
• 48-inch section length reduces joint count on long trunk runs
• Manufactured to ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style rectangular trunk duct section for use in standard forced-air HVAC supply systems requiring a 24-inch by 10-inch galvanized steel main trunk configuration.

Installation Notes

Installation should be performed by a qualified HVAC sheet metal mechanic following SMACNA duct construction standards and local mechanical code requirements. Power down and lock out the air handling equipment before connecting or modifying ductwork sections. Use appropriate S-cleat and drive clips to secure adjoining sections, and seal all longitudinal seams and end joints with UL 181-listed duct sealant or mastic per applicable code. Support the trunk duct at intervals consistent with SMACNA hanger and support requirements for the installed weight and span.
