Hart Cooley 050299 T-bar Diffuser Frame 24x24 Aluminum

Product Description

The HART COOLEY 050299 is a surface-mount T-bar diffuser frame designed to allow installation of standard T-bar diffusers in plaster ceilings. Constructed from aluminum, the frame measures 24 inches by 24 inches and provides a clean, stable mounting interface between the ceiling surface and the diffuser. HVAC technicians and mechanical contractors use this frame where a suspended T-bar grid is not present but a standard T-bar diffuser must still be installed. The aluminum construction keeps weight low while offering reliable dimensional stability in typical commercial and residential ceiling applications.

This frame is suited for retrofit and new-construction scenarios where plaster or hard-lid ceilings require a T-bar diffuser fitting. It is surface-mounted directly to the ceiling, bridging the gap between a solid ceiling substrate and a standard T-bar diffuser. Common applications include commercial office spaces, healthcare facilities, schools, and residential installations where hard ceilings are specified and T-bar diffusers are the supply air terminal of choice.

Key Features

• Aluminum construction for lightweight, corrosion-resistant performance
• Surface-mount design installs directly onto plaster or hard-lid ceilings
• Accepts standard T-bar diffusers without modification
• 24 inch by 24 inch frame size matches common diffuser module dimensions

Compatibility

Designed to accept standard T-bar diffusers in surface-mount applications on plaster ceilings where a suspended T-bar grid ceiling system is not present.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal contractor. Secure the frame to the ceiling substrate using appropriate fasteners for the ceiling material before inserting the diffuser. Ensure the duct collar connection is made and airflow is confirmed before final diffuser seating. Shut down the air handling unit before making duct connections or securing the frame to prevent accidental airflow during installation.
