Metal-fab l3c8 3-cone Square Diffuser 24x24 in 8 in Collar

Product Description

The METAL-FAB l3c8 is a 3-cone square ceiling diffuser designed for commercial HVAC air distribution. Built from heavy-gauge sheet metal with a white finish, it features an innovative adjustable cone design that allows the cones to sit flush with the face plate for a clean, low-profile appearance, or to be extended outward for maximum airflow delivery. The 8-inch collar connects to standard round duct and the overall face dimensions measure 24 inches by 24 inches. This diffuser is installed by HVAC technicians in commercial ceiling grid or hard-lid ceiling applications where controlled, multi-directional air distribution is required.

This diffuser suits commercial spaces where 3-way air deflection is needed across a ceiling plane. The square face fits standard 24-inch by 24-inch ceiling openings commonly found in drop-ceiling commercial environments. The adjustable cone position lets the installing technician tune airflow pattern on-site without additional hardware, making it practical for variable-occupancy spaces, open office layouts, retail floors, and similar commercial installations.

Key Features

• Adjustable 3-cone design allows flush or extended position to control airflow pattern
• 3-way deflection distributes air in multiple directions across the occupied zone
• Heavy-gauge sheet metal construction for durability in commercial installations
• 24 x 24 inch square face fits standard commercial ceiling grid openings
• 8-inch collar for direct connection to round supply duct
• White finish blends with standard commercial ceiling tile and grid systems

Compatibility

Designed as an OEM-style replacement or new-installation diffuser for commercial HVAC supply air systems using 8-inch round duct with a 24-inch by 24-inch ceiling opening.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut off the air handling unit and confirm zero airflow at the duct before beginning installation. Secure the 8-inch collar to the supply duct using appropriate fasteners and duct sealant per local mechanical code requirements. Adjust cone position after system restart to achieve the desired airflow pattern for the space.
