The SOUTHWARK METAL 31PF4X10 is a plaster frame designed for use with flush-mounted HVAC registers and grilles in plaster or drywall ceiling and wall applications. Plaster frames provide a finished border that allows installers to complete plasterwork or drywall mud work around a register opening before the grille is set. This frame measures 4 inches by 10 inches, sized to fit a standard 4x10 duct opening. It is typically installed by HVAC contractors and finish tradespeople working on new construction or renovation projects where a clean, flush transition between the wall surface and the register is required.
The 31PF4X10 is suited for residential and light commercial HVAC ducting systems where 4x10 inch supply or return air openings are used. It is commonly installed in plaster ceilings, drywall ceilings, and plaster wall applications. The frame is set during the rough-in or finishing phase before the final register or grille is placed, ensuring proper alignment and a clean finished appearance at the opening.
Designed as an OEM-style replacement or new-installation plaster frame for standard 4x10 inch HVAC register and grille openings in plaster and drywall applications.
Installation is typically performed by HVAC or finish trade contractors during the rough-in or plastering phase of construction. The frame should be secured to the duct collar or surrounding structure before plaster or drywall compound is applied. Ensure the duct system is not pressurized and work area is clear before beginning installation. Follow applicable local mechanical codes for register and grille placement requirements.
