Southwark Metal TD_26X12X60 Sheet Metal Trunk Duct

Product Description

The SOUTHWARK METAL TD_26X12X60 is a rectangular sheet metal trunk duct section manufactured from hot-dip galvanized steel for use in forced-air HVAC distribution systems. Measuring 26 inches by 12 inches in cross-section and 60 inches in length, this duct section is built to ACCA and SMACNA standards. It features a button snap-lock seam with S-cleat and drive connection ends for secure field assembly, and a cross-broken panel construction that adds rigidity to the flat faces. Licensed HVAC technicians and sheet metal contractors install this duct as part of trunk-and-branch or extended-plenum supply air systems.

This trunk duct section is suited for residential and light commercial forced-air supply systems where a large rectangular main trunk is required. The 26 by 12 inch profile accommodates high-volume airflow runs off the air handler or furnace plenum. The button snap-lock seam and drive-and-cleat end connections allow consecutive sections to be joined on the job site without specialized tooling, making it appropriate for new construction and retrofit trunk extensions alike.

Key Features

• Hot-dip galvanized steel construction for corrosion resistance in conditioned and unconditioned spaces
• Button snap-lock longitudinal seam for secure, airtight panel closure
• S-cleat and drive connection ends for fast, tool-friendly field assembly of consecutive sections
• Cross-broken panel faces for added structural rigidity on the 26-inch dimension
• Manufactured to ACCA and SMACNA applicable standards
• 60-inch section length reduces the number of joints required on long trunk runs

Compatibility

Designed as an OEM-style rectangular trunk duct section for residential and light commercial forced-air HVAC supply air distribution systems using standard drive-and-cleat and S-cleat connection methods per SMACNA duct construction guidelines.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor in accordance with SMACNA duct construction standards and local mechanical codes. Power down the air handling unit and close the fuel or refrigerant supply before connecting new duct sections to an existing system. Sections should be properly supported with hangers or strapping at intervals consistent with SMACNA hanger spacing requirements. Seal all longitudinal seams and transverse joints with UL 181-listed mastic or approved metal foil tape to meet duct leakage requirements.
