Southwark Metal 48_32X35 Trunk Duct Panning 32x35 in

Product Description

The SOUTHWARK METAL 48_32X35 is a double-material sheet metal trunk duct panning section used in forced-air HVAC duct systems. Fabricated from hot dip galvanized steel, this panning material is designed to close off the bottom of floor joist or framed cavities, converting the cavity into a return-air or supply duct trunk. It measures 32 inches x 35 inches, making it suited for larger trunk applications in residential and light commercial construction. HVAC installers and sheet metal contractors use this component during new construction or retrofit ductwork projects where building cavities serve as part of the air distribution system.

This panning material is used in forced-air systems where floor joist bays or framed chases are used as trunk ducts. It is installed by sheet metal contractors and HVAC technicians during rough-in or retrofit work. Typical applications include residential new construction and remodel projects where a panned joist return or supply trunk is part of the duct design. Compliance with ACCA and SMACNA standards makes it appropriate for installations that must meet those specifications.

Key Features

• Hot dip galvanized steel construction for corrosion resistance in air-handling environments
• 32 inches x 35 inches size accommodates larger trunk duct cavities
• Meets ACCA and SMACNA applicable standards for duct construction
• Double material designation provides added rigidity for spanning wider cavities
• Designed for use as floor or wall cavity panning in trunk duct applications

Compatibility

Designed as an OEM-style sheet metal panning component for use in residential and light commercial forced-air trunk duct systems built to ACCA and SMACNA standards.

Installation Notes

Installation is performed by licensed HVAC technicians or sheet metal contractors following SMACNA duct construction standards and applicable local mechanical codes. The air-handling system should be powered down and the system should not be under pressure before fitting panning material into the cavity. Edges are typically fastened with sheet metal screws or drive cleats, and seams should be sealed with UL 181-rated mastic or tape per code requirements. Wear appropriate cut-resistant gloves when handling sheet metal edges.
