The METAL-FAB l3c6 is a 3-cone square ceiling diffuser designed for commercial HVAC air distribution. Built from heavy-gauge sheet metal with a clean white finish, this diffuser features an innovative adjustable cone design that can be set flush for a sleek appearance or extended outward to maximize airflow. The unit measures 24 inches by 24 inches with a 6-inch collar for duct connection. It provides 3-way deflection, spreading conditioned air efficiently across the space. HVAC technicians and mechanical contractors install this type of diffuser in suspended ceiling systems as part of a supply-air distribution layout.
This diffuser is suited for commercial installations where both performance and aesthetics matter. The adjustable cone position allows the installer to tune airflow pattern to the room layout without additional hardware. The 24 inch by 24 inch face plate fits standard 2-foot by 2-foot ceiling grid openings common in drop-ceiling commercial environments. The 6-inch collar connects directly to round supply-air branch ductwork. It is appropriate for office spaces, retail environments, and similar light commercial applications where a clean ceiling appearance is required alongside reliable air distribution.
Designed as an OEM-style replacement or new-install diffuser for commercial drop-ceiling HVAC supply-air systems using 6-inch round collar connections and standard 2-foot by 2-foot ceiling grid openings.
Installation is performed by licensed HVAC technicians or qualified mechanical contractors. Shut off the air handling unit and relieve system pressure before connecting the collar to the branch duct. Secure the diffuser to the ceiling grid per local mechanical code requirements and ensure the collar connection is properly sealed to prevent air leakage. Do not overtighten the grid mounting hardware, as this may distort the sheet metal face.
