Metal-Fab has added these light-commercial diffusers to its line of grilles and registers. The diffusers are available in two-cone, three-cone and perforated models. The two- and three-cone models feature an exclusive design that adjusts to allow a flush look or can be pulled into extended position for maximum airflow. Both models are available with or without insulation. Collar design features a long 2 1/4-inch collar for easy flex-duct connection, and slots for attachment of butterfly damper. The 2x2 perforated model features a preformed insulation shell as standard. They are also available as a return grille configuration. All Metal-Fab 2x2 diffusers are constructed with heavy-gauge steel and a premium powder-coat finish, individually packaged with corner and collar pads for protection in shipping.
