The SOUTHWARK METAL 31PF-16GA_6X12 is a sheet metal duct plaster frame boot rail designed for return air duct terminations in residential and light commercial construction. Built from hot dip galvanized steel at 16 gauge thickness, this frame provides a rigid, corrosion-resistant border that holds drywall or plaster surfaces cleanly against the duct opening. It is used during new construction and renovation work where a finished, flush grille mount is required at the wall or ceiling. HVAC installers and sheet metal contractors fit this component into framed cavities before drywall is applied, ensuring a clean border for the return air grille.
This plaster frame boot rail is suited for return air applications in ducted forced-air systems. The 6 inch x 12 inch frame size matches standard boot openings of the same dimension and is appropriate for residential construction and light commercial projects where SMACNA and ACCA installation standards apply. It is typically installed at wall, floor, or ceiling penetrations where a return air grille will be surface-mounted over finished drywall or plaster.
Designed as an OEM-style sheet metal component for return air duct terminations in residential and light commercial forced-air HVAC systems requiring a 6 inch x 12 inch plaster frame boot rail.
Installation is typically performed by licensed HVAC technicians or sheet metal contractors during the rough-in phase, before drywall or plaster is applied. The frame should be secured to framing or the duct boot prior to wall finishing. Comply with applicable SMACNA and ACCA ductwork installation standards for your jurisdiction. Power down the air handling system before working on any connected ductwork components.
