Southwark Metal TD_26X10X60 Trunk Duct 26x10x60

Product Description

The SOUTHWARK METAL TD_26X10X60 is a rectangular sheet metal trunk duct section used to distribute conditioned air in forced-air HVAC systems. Fabricated from hot dip galvanized steel, it measures 26 inches by 10 inches in cross-section and 60 inches in length. The section assembles using a button snap-lock seam with S-cleat and drive connection ends, providing a secure, airtight joint without specialty tooling. Cross-breaking on the panel faces adds rigidity and reduces oil-canning under system pressure. HVAC sheet metal installers and mechanical contractors are the primary trade for this component.

This trunk duct section is suited for residential and light commercial forced-air installations where rectangular galvanized ductwork is specified. It is used as a main supply trunk or extended plenum run connecting the air handler or furnace to branch takeoffs. The 26-by-10-inch profile accommodates moderate-to-high airflow applications in standard ceiling, attic, basement, and crawlspace installations. Its factory-fabricated ends allow field assembly in line with SMACNA and ACCA duct construction standards without additional forming.

Key Features

• Hot dip galvanized steel construction resists corrosion in unconditioned spaces
• Button snap-lock seam provides a secure longitudinal joint for assembly speed and air tightness
• S-cleat and drive connection ends allow field-joining to adjacent duct sections and fittings
• Cross-broken panel faces increase rigidity and reduce noise and deflection under airflow pressure
• Meets ACCA and SMACNA applicable standards for residential and commercial sheet metal ductwork
• 60-inch length reduces the number of joints required in long trunk runs

Compatibility

Designed as an OEM-style replacement and new-construction component for rectangular galvanized sheet metal duct systems assembled with standard S-cleat and drive connections per SMACNA and ACCA duct construction guidelines.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal mechanic in accordance with SMACNA duct construction standards and local mechanical codes. Power down the air handling unit and close the main disconnect before connecting duct sections to an existing system. S-cleat and drive connections should be secured and sealed with listed duct sealant or mastic per applicable code to meet leakage requirements. Support spacing should follow SMACNA hanger and support guidelines for the duct size and weight.
