Southwark Metal TD_16X10X48 Sheet Metal Trunk Duct

Product Description

The SOUTHWARK METAL TD_16X10X48 is a rectangular sheet metal trunk duct section used in forced-air HVAC distribution systems. Fabricated from hot dip galvanized steel, this duct section measures 16 inches by 10 inches in cross-section and 48 inches in length. It features button snap-lock assembly with an S-cleat and drive connection, and includes cross-breaking on the panels for added rigidity. HVAC installers and sheet metal contractors use this duct section when building out main trunk lines in residential and light commercial air distribution systems.

This trunk duct section is suited for new construction and retrofit trunk-and-branch duct systems where a 16-inch by 10-inch rectangular main or sub-main is specified. The 48-inch length allows efficient layout with fewer joints per run. The S-cleat and drive connection ends make field assembly straightforward with standard sheet metal tools. Cross-breaking reduces oil-canning and helps the duct hold its shape under system pressure. Fabricated to ACCA and SMACNA applicable standards, making it compatible with engineered duct designs that reference those specifications.

Key Features

• Hot dip galvanized steel construction for corrosion resistance in conditioned and unconditioned spaces
• Button snap-lock seam with S-cleat and drive connection ends for field assembly without additional fabrication
• Cross-broken panels reduce flex noise and maintain panel stiffness under static pressure
• 48-inch section length reduces total joint count per trunk run
• Fabricated to ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style rectangular trunk duct section for use in forced-air residential and light commercial HVAC duct systems where a 16-inch by 10-inch cross-section trunk line is specified per load calculation and duct design.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal contractor following SMACNA duct construction standards and local mechanical codes. Shut down the air handler or furnace and verify the system is de-energized before connecting to any existing ductwork. Use drive cleats, S-cleats, and approved duct sealant or mastic at all joints to meet leakage requirements per the applicable energy code. Support the duct at intervals per SMACNA hangar spacing guidelines to prevent sag and joint separation.
