Cover a 18 x 18 in. nominal return air opening with a white, stamped steel grille. Its fixed louvers are spaced 1/2 in. apart and angled at 40 degrees for return airflow. This model has no filter frame, so any air filter must be located elsewhere in the system.

• Nominal opening: 18 x 18 in. (width first)
• Overall face: 19-3/4 x 19-3/4 in.; measure the space available around the opening
• All-steel construction with a white finish
• Mounting screws included

Check both the opening and outside face dimensions before ordering.
