Southwark Metal TD_20X10X48 Sheet Metal Trunk Duct 20x10x48

Product Description

The SOUTHWARK METAL TD_20X10X48 is a rectangular sheet metal trunk duct section manufactured from hot-dip galvanized steel. It measures 20 inches wide by 10 inches tall by 48 inches long and is built for use in forced-air HVAC distribution systems. The section features a button snap-lock seam with S-cleat and drive connection ends for field assembly, and cross-breaking on the face panels to reduce drumming and improve rigidity. This trunk duct section is installed by licensed HVAC technicians and sheet metal contractors during new construction or system renovation work.

This trunk duct section is used in residential and light commercial forced-air supply or return main trunk runs. The 20 by 10 inch cross-section suits medium-capacity air distribution systems where space constraints or design loads call for a low-profile rectangular main. The 48-inch length reduces joint count in straight runs, which helps maintain system efficiency and reduces potential leak points. Compatible with standard S-cleat and drive slip fittings used throughout rectangular duct fabrication and installation.

Key Features

• Hot-dip galvanized steel construction for corrosion resistance in conditioned and unconditioned spaces
• Button snap-lock seam for fast, consistent longitudinal closure in the field
• S-cleat and drive connection ends for straightforward inline joining to adjacent sections or fittings
• Cross-broken face panels reduce sheet flexing and noise under airflow pressure
• 48-inch section length minimizes joint count in long trunk runs
• Manufactured to ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style rectangular trunk duct section compatible with standard S-cleat and drive slip assembly systems used in residential and light commercial forced-air ductwork installations.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal contractor in accordance with SMACNA duct construction standards and local mechanical codes. Power down and lock out the air handling unit before connecting or modifying any trunk duct section. Secure all S-cleat and drive connections fully before applying duct sealant or tape at joints to meet applicable leakage class requirements. Support hangers should be spaced per SMACNA guidelines for the duct weight and cross-section size.
