Added to the company’s line of grilles and registers are the 2- by 2-foot light commercial diffusers. The diffusers are available in two-cone, three-cone, and perforated models. The two-and three-cone models feature a design that is adjustable to allow a sleek, flush look, or that can be pulled into an extended position for maximum airflow. Both models are available with or without insulation. Collar design features a long, 2-1/4-inch collar for flex duct connection, and slots for attaching butterfly dampers. The perforated model features a preformed insulation shell as standard. It is also available as a return grille configuration. The diffusers are constructed with heavy-gauge steel and have a powder-coat finish.
