Frequently Asked Questions

What size do I order — 6x12 or face size?
Order by duct opening size (6" × 12"). The face size (7-3/4" × 13-3/4") overlaps the opening.

Is this for supply air or return air?
Supply air, with adjustable airflow. For return air, see the 6x12 return air grille.

Will the black finish fade or chip?
No — it's a matte black powder coat baked onto solid aluminum, not paint over plastic.

Is a white finish available?
Yes — see the 6x12 White Linear Slot Diffuser.

Is there a Slim / trimless version?
Yes — see the 6x12 Slim Design Linear Slot Diffuser for shallow-duct installs.
