Southwark Metal 31PF-16GA_6X10 Duct Plaster Frame 6x10 16 Gauge

Product Description

The SOUTHWARK METAL 31PF-16GA_6X10 is a sheet metal duct plaster frame boot rail designed for return air applications in residential and light commercial HVAC duct systems. Constructed from hot dip galvanized steel at 16 gauge, this plaster frame provides a rigid, corrosion-resistant border around a 6-inch by 10-inch duct opening where the boot meets a wall, ceiling, or floor finish plane. It holds the rough opening square during plastering, drywalling, or tile work and gives the grille or register a clean, solid surface to mount against. HVAC sheet metal installers and rough-in crews use this component during new construction and remodel projects to meet ACCA and SMACNA installation standards.

This plaster frame is suited for return air duct boot terminations in framed wall cavities, floor installations, and ceiling applications where a finished surface is applied over the structural framing. It is commonly installed during the rough-in phase before wall board or plaster is applied, ensuring the duct opening is protected and dimensionally stable throughout the finishing process. The 6-inch by 10-inch frame size accommodates standard duct openings of that nominal dimension.

Key Features

• Hot dip galvanized steel construction resists corrosion in both conditioned and unconditioned spaces
• 16 gauge material thickness provides rigid support during wall, floor, or ceiling finishing work
• 6-inch by 10-inch frame size fits standard nominal duct boot openings
• Return air configuration for use on the suction side of the air distribution system
• Meets ACCA and SMACNA applicable standards for sheet metal duct fabrication and installation

Compatibility

Designed as an OEM-style sheet metal component for return air boot terminations in residential and light commercial forced-air duct systems conforming to ACCA and SMACNA guidelines.

Installation Notes

Installation is performed by licensed HVAC technicians or sheet metal mechanics during the rough-in phase of construction. The frame should be secured to the framing or substrate before finish surfaces are applied. Follow SMACNA duct construction standards and local mechanical code requirements for fastener type and spacing. Ensure the duct system is de-energized and the air handler is shut down before making any connections to the return air plenum or duct network.
