Southwark Metal TD_8X8X60 Sheet Metal Trunk Duct 8x8x60

Product Description

The SOUTHWARK METAL TD_8X8X60 is a rectangular sheet metal trunk duct section built for supply air distribution in residential and light commercial forced-air HVAC systems. Manufactured from hot dip galvanized steel, it measures 8 inches by 8 inches in cross-section and 60 inches in length. The duct features a button snap-lock seam with S-cleat and drive connection ends, allowing fast, secure field assembly without additional fasteners. Cross breaking on the flat panels adds rigidity and reduces oil-canning under static pressure. This is a standard fabricated duct section installed by HVAC sheet metal mechanics and service technicians during system installation or retrofit work.

This trunk duct section is suited for low-pressure supply air trunk and branch applications in residential and small commercial forced-air systems. It connects to air handlers, furnace plenums, or other duct sections using standard S-cleat and drive slip connections, which are common on rectangular galvanized duct installations. The 8 by 8 inch profile is a widely used size for main trunk runs and larger branch takeoffs where moderate airflow capacity is required. Fabrication meets ACCA and SMACNA standards for rectangular sheet metal ductwork.

Key Features

• Hot dip galvanized steel construction resists corrosion in conditioned air environments
• Button snap-lock seam provides a tight longitudinal closure without field welding or additional sealant
• S-cleat and drive connection ends for fast, standard field assembly with adjoining duct sections
• Cross broken flat panels add structural rigidity and reduce panel flex under operating pressure
• Fabricated to ACCA and SMACNA standards for low-pressure rectangular duct systems
• 60-inch section length reduces the number of joints needed on long trunk runs

Compatibility

Designed as an OEM-style replacement and new-construction rectangular trunk duct section compatible with standard S-cleat and drive slip connection rectangular duct systems following SMACNA and ACCA duct construction guidelines.

Installation Notes

Installation should be performed by a qualified HVAC technician or sheet metal mechanic in accordance with SMACNA duct construction standards and local mechanical codes. Power down the air handling system before cutting into or modifying existing ductwork. Seal all longitudinal seams and transverse joints with listed duct sealant or mastic per applicable code requirements to meet air leakage standards. Support duct sections at intervals required by SMACNA hanger and support specifications to prevent sag and joint separation.
