Southwark Metal TD_25X10X48 Sheet Metal Trunk Duct

Product Description

The SOUTHWARK METAL TD_25X10X48 is a rectangular sheet metal trunk duct section built for commercial and residential forced-air distribution systems. Fabricated from hot dip galvanized steel, this duct section measures 25 inches wide by 10 inches tall by 48 inches long. It features a button snap-lock seam with S-cleat and drive connection ends for secure, field-ready assembly. Cross breaking on the panels adds rigidity and reduces noise from thermal expansion. Licensed sheet metal workers and HVAC installers use this trunk section as a primary supply or return air distribution component in low-pressure duct systems.

This trunk duct section is suited for new construction and retrofit installations in residential and light commercial HVAC systems. The 25 x 10 inch cross-section accommodates high-volume airflow in main trunk runs. The 48-inch length allows efficient layout planning with fewer joints. The drive and S-cleat connection system is a standard field-assembly method that speeds up installation while maintaining a tight, low-leakage joint when properly sealed. This section is fabricated to ACCA and SMACNA standards, making it appropriate for jobs where specification compliance is required.

Key Features

• Hot dip galvanized steel construction for corrosion resistance in interior duct applications
• Button snap-lock seam provides a secure longitudinal closure along the duct body
• S-cleat and drive connection ends allow fast, standard field assembly with adjacent duct sections
• Cross-broken panels add structural rigidity and reduce oil-canning and drumming
• Fabricated to ACCA and SMACNA applicable standards for specification-compliant installations
• 48-inch section length reduces joint count in long trunk runs

Compatibility

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

Installation Notes

Installation should be performed by a licensed sheet metal worker or qualified HVAC technician following SMACNA duct construction standards and local mechanical code requirements. Power down the air handling unit before connecting or sealing duct sections. All longitudinal seams and transverse joints should be sealed with listed duct sealant or approved tape per SMACNA and energy code requirements. Support spacing and hanger methods must comply with SMACNA hanger and support guidelines for the duct size and system pressure class.
