The HART COOLEY 013242 is a steel diffuser installation frame designed to provide a clean, secure mounting surface for ceiling or wall air diffusers in residential and light commercial HVAC applications. The frame accommodates a 10-inch by 10-inch duct opening and features a Golden Sand enamel finish that blends with standard interior surfaces. The overall frame dimensions measure 11-13/16 inches wide by 11-13/16 inches tall by 1 inch deep, providing a flush, finished appearance around the diffuser. HVAC technicians and installers use this frame to create a professional termination point at the grille or diffuser location during new construction or renovation work.
This installation frame is suited for use in forced-air duct systems where a 10-inch by 10-inch square duct opening requires a finished transition to a surface-mounted diffuser. It is commonly installed in drop ceilings, drywall ceilings, and wall assemblies. The Golden Sand enamel finish makes it appropriate for spaces where a neutral, coordinated appearance is required. It is typically installed by HVAC contractors or sheet metal installers during rough-in or finish work.
Designed as an OEM-style installation frame for use with 10-inch by 10-inch square HVAC diffusers in residential and light commercial forced-air duct systems.
Installation is typically performed by a licensed HVAC technician or sheet metal installer. Power down the air handling system before beginning any duct termination or grille framing work. The frame should be secured firmly to the ceiling or wall substrate to ensure the diffuser seats properly and air leakage around the border is minimized. Follow local mechanical codes for duct termination requirements.
