Southwark Metal 31PF-24GA_6X10 Duct Plaster Frame 6x10 24GA

Product Description

The SOUTHWARK METAL 31PF-24GA_6X10 is a sheet metal duct plaster frame boot rail designed for return air duct terminations in residential and light commercial HVAC installations. Fabricated from hot dip galvanized steel at 24 gauge, this frame provides a rigid, corrosion-resistant border that secures the duct boot opening against finish surfaces such as drywall or plaster. The 6 x 10 inch frame size fits standard return air boot openings and holds dimensional stability during and after wall or ceiling finishing work. HVAC sheet metal contractors and duct installers use this component to create a clean, code-consistent transition at the rough-in stage before grilles or registers are applied.

This plaster frame is suited for return air duct systems in new construction and remodel projects where boots are installed before finish surfaces are applied. It is placed around the boot opening to protect the duct edge and provide a flush nailing or fastening surface against framing or backing. Typical applications include floor, wall, and ceiling return air openings in forced-air systems. The 6 x 10 inch opening dimension corresponds to standard register and grille sizing used across residential forced-air duct layouts built to ACCA and SMACNA standards.

Key Features

• Hot dip galvanized steel construction resists corrosion in humid or unconditioned spaces
• 24 gauge material thickness provides rigid support at the boot-to-finish-surface interface
• 6 x 10 inch frame size matches standard return air boot and register opening dimensions
• Designed for return air duct applications in residential and light commercial systems
• Meets ACCA and SMACNA applicable standards for sheet metal duct fabrication

Compatibility

Designed as an OEM-style sheet metal duct component for use with standard 6 x 10 inch return air boot openings in residential and light commercial forced-air duct systems built to ACCA and SMACNA guidelines.

Installation Notes

Installation is typically performed by licensed HVAC sheet metal contractors or journeymen duct installers during the rough-in phase, before wall or ceiling finish surfaces are applied. Shut down the air handling system before working on any duct components. Secure the plaster frame to the framing or boot flange using appropriate sheet metal screws or fasteners per SMACNA duct construction standards. Avoid over-fastening or distorting the frame, as dimensional accuracy affects grille and register fit at final trim-out.
