Installation

- Mount with the included screws through the hidden side holes.
- Use the Deflector Bar to set airflow direction.
Frequently Asked Questions
What's the difference between this and the standard 4x10 diffuser?
The Slim Design has a shallower 1-1/4" neck depth — it fits ducts too shallow for our standard-depth diffusers, without changing face size or airflow.
What size do I order — 4x10 or face size?
Order by duct opening size (4" × 10"). The face size (11-3/4" × 5-13/16") overlaps the opening.
Is this for supply air or return air?
Supply air, with adjustable airflow. For return air in this size, see our 4x10 return air grille.
Can I install this on a floor?
Yes — mounts on walls, ceilings, or floors.
Is a black finish available?
This Slim Design size is currently White only. See the standard-depth 4x10 Black Linear Slot Diffuser instead.
