Southwark Metal 31PF-24GA_6X14 Plaster Frame Boot Rail 6x14

Product Description

The SOUTHWARK METAL 31PF-24GA_6X14 is a sheet metal duct plaster frame boot rail designed for return air duct terminations in residential and light commercial HVAC systems. Fabricated from hot dip galvanized steel at 24 gauge, this plaster frame provides a clean, rigid border around the duct boot opening where the register or grille seats against a finished wall or ceiling surface. It is installed by sheet metal workers and HVAC technicians during rough-in to hold the duct boot flush with drywall or plaster finishes. The frame measures 6 inches by 14 inches, matching the duct opening, and conforms to ACCA and SMACNA fabrication standards.

This plaster frame boot rail is used in return air applications where a flush, finished appearance is required at the wall or ceiling plane. It is typically installed during the framing or rough-in phase before drywall is applied, allowing the duct boot to be set at the correct depth relative to the finished surface. Suitable for residential new construction and renovation projects where ducted return air systems are built to SMACNA sheet metal standards.
