Supply air, with adjustable airflow. For return air in this size, see our 8x8 return air grille.

Why does this have 4 slots instead of 2?
Larger duct openings use more slots to keep face velocity comfortable and reduce airflow noise — 4 slots spread the air across a wider face.

Can I install this on a ceiling?
Yes — mounts on walls or ceilings.

Is a black finish available?
This size is currently White only. See the full linear slot diffuser collection for Black options in other sizes.
