Southwark Metal TD_22X10X48 Sheet Metal Trunk Duct

Product Description

The SOUTHWARK METAL TD_22X10X48 is a rectangular sheet metal trunk duct section used in forced-air HVAC distribution systems. Fabricated from hot-dip galvanized steel, it measures 22 inches wide by 10 inches tall by 48 inches long and ships ready for field assembly. The section features button snap-lock construction with S-cleat and drive connection ends, and cross-breaking on the flat panels to increase rigidity and resist oil-canning. Licensed HVAC technicians and sheet metal contractors install this type of section as part of a low-pressure supply or return trunk line in residential and light commercial ductwork systems.

This trunk duct section is suited for new construction and renovation work where main trunk runs are fabricated from rectangular sheet metal. The 22-inch by 10-inch cross-section accommodates high-volume airflow requirements in larger residential systems or smaller commercial applications. The 48-inch length is a standard field section that works within conventional trunk-and-branch layouts. S-cleat and drive connections allow it to join directly to matching duct sections, transitions, and fittings without special tooling beyond standard sheet metal hand tools.

Key Features

• Hot-dip galvanized steel construction resists corrosion in attic, crawlspace, and mechanical room installations
• Button snap-lock seam with S-cleat and drive connections for fast, secure field assembly
• Cross-broken panels add structural rigidity and reduce noise from panel flexing under static pressure
• 22 x 10 x 48 inch dimensions fit standard rectangular trunk duct layouts
• Meets ACCA and SMACNA applicable standards for sheet metal ductwork fabrication

Compatibility

Designed as an OEM-style replacement and new-construction trunk duct section compatible with standard rectangular sheet metal duct systems using S-cleat and drive connections, per SMACNA and ACCA ductwork guidelines.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal contractor following SMACNA duct construction standards and applicable local mechanical codes. Shut down the air handling unit and isolate the system before cutting into or extending an existing trunk line. Use aviation snips, a drive-cleat tool, and S-cleat stock to secure joints; seal all longitudinal seams and transverse connections with UL 181-rated mastic or foil tape as required by code. Support the duct at intervals consistent with SMACNA hanger spacing requirements for the duct size and weight.
