Southwark Metal 31PF4X12 Plaster Frame 4x12

Product Description

The SOUTHWARK METAL 31PF4X12 is a plaster frame designed for use with wall and ceiling registers in plastered surfaces. This frame provides a clean, flush mounting border that supports the register face during plaster application and finishing work, maintaining precise opening dimensions after the wall surface is complete. It is installed by sheet metal contractors, HVAC technicians, and finish carpenters during rough-in and finishing stages of construction. The frame measures 4 x 12 inches, making it a standard size suited for residential and light commercial duct terminations.

This plaster frame is used in new construction and remodel projects where walls or ceilings receive a plaster or hard-coat finish. It is set into the framed opening prior to plaster application, holding the register opening square and protecting the duct collar during the finishing process. Typical installations include residential HVAC supply and return air grille locations in plaster-walled homes and buildings where standard drywall frames are not appropriate.

Key Features

• 4 x 12 inch opening size suited for standard residential register applications
• Designed to maintain precise opening dimensions through plaster application
• Compatible with wall and ceiling register installations in plaster surfaces
• Supports flush, professional finishing at grille and register locations

Compatibility

Designed as an OEM-style replacement and new-installation plaster frame for use with 4 x 12 inch wall and ceiling registers in plastered residential and light commercial HVAC applications.

Installation Notes

Installation is typically performed by sheet metal contractors or HVAC technicians during the rough-in phase, before plaster is applied. Shut down the HVAC system before working at any duct termination point. Secure the frame firmly to the surrounding framing to prevent movement during plastering. Verify the opening remains square and unobstructed before installing the register face plate.
