Southwark Metal TD_26X10X48 Sheet Metal Trunk Duct

Product Description

The SOUTHWARK METAL TD_26X10X48 is a rectangular sheet metal trunk duct section designed for low-pressure forced-air distribution systems in residential and light commercial HVAC applications. Fabricated from hot dip galvanized steel, this duct section measures 26 inches wide by 10 inches tall by 48 inches long and connects using a button snap-lock seam with S-cleat and drive connection hardware. Cross breaking on the flat panels adds structural rigidity to the duct walls, reducing flex noise and maintaining shape under static pressure. Licensed HVAC installers and sheet metal contractors use this type of duct section to build or extend supply air trunk lines from an air handler or furnace plenum.

This trunk duct section is suited for new construction and retrofit supply air systems in residential homes, light commercial spaces, and modular buildings where rectangular duct runs are specified. The 26-by-10-inch cross section accommodates high-volume trunk line runs where airflow capacity and rigid construction are required. It is compatible with standard S-cleat and drive-strip connections used throughout conventional sheet metal duct systems built to SMACNA and ACCA standards.

Key Features

• Hot dip galvanized steel construction resists corrosion in unconditioned spaces such as attics, crawlspaces, and basements
• Button snap-lock longitudinal seam with S-cleat and drive connection for secure field assembly without additional fasteners
• Cross-broken flat panels reduce oil-canning and flex noise under system static pressure
• 26 x 10 inch cross section supports high-volume trunk line airflow distribution
• Meets SMACNA and ACCA applicable standards for sheet metal duct fabrication
• 48-inch section length reduces joint count in straight trunk runs

Compatibility

Designed as an OEM-style replacement and new-construction trunk duct section compatible with standard S-cleat and drive-strip rectangular duct systems built to SMACNA and ACCA specifications.

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 the air handling unit or furnace before connecting or modifying any duct section downstream of the supply plenum. Secure all S-cleat and drive connections fully and seal longitudinal and transverse joints with UL 181-rated mastic or foil tape as required by local code. Support duct sections at intervals per SMACNA hanger and support guidelines to prevent sagging and joint separation over time.
