The Southwark Metal 11065 is a 60-inch plaster round designed for use in HVAC duct and ceiling applications where a clean, finished opening is required. Plaster rings provide the structural border around a ceiling or wall penetration, supporting the surrounding finish material and creating a defined edge for grille or diffuser installation. This round format measures 60 inches, making it suited for larger-diameter openings in commercial or industrial settings. HVAC sheet metal contractors and installers work with this component during rough-in and finish phases of duct system construction.
Plaster rounds of this size are typically installed in ceiling assemblies during construction or renovation projects where ductwork terminates at a ceiling plane. The 60-inch diameter positions this unit for large-scale air distribution systems in commercial buildings, industrial facilities, or institutional spaces. It provides a stable mounting surface and a finished perimeter for the final grille or diffuser that completes the air outlet.
Designed as an OEM-style sheet metal component for use with round duct terminations and ceiling assemblies requiring a 60-inch plaster ring finish border.
Installation is typically performed by licensed HVAC sheet metal contractors during the rough-in or finish phase of construction. Shut down the air handling system before working on or around the duct opening. Ensure the ceiling substrate or framing is structurally adequate to support the ring and any grille or diffuser attached to it. Follow local mechanical codes and manufacturer guidelines for securing sheet metal components to ceiling assemblies.
