8"x8" 3-Way White Aluminum Square Ceiling Diffuser, Rust-Proof Ceiling Supply Grille

Product Overview

The 8"W x 8"H white aluminum square ceiling diffuser carries supply air into the room through a ceiling opening. Extruded aluminum resists rust in humid rooms, a stronger choice than lightweight plastic covers. The 3-way blade pattern directs air across the room. Select this square ceiling diffuser by its duct opening size, not the overall face size, so it seats correctly on the first fit.

Key Features

• Aluminum construction: Aluminum keeps the square ceiling diffuser rigid during installation and resists warping over time.
• White finish: The white finish coordinates with common flooring, trim, and hardware.
• 3-Way air pattern: The 3-way throw sends conditioned air where the space needs it.
• Right-fit sizing: Ordered by duct opening size, this square ceiling diffuser matches standard duct dimensions and cuts wrong-size returns.

Dimensions and Specifications

Is This the Right Vent for Your Opening?

Choose this square ceiling diffuser if you need a supply-air vent for a ceiling opening. This square ceiling diffuser carries supply air and mounts on ceiling surfaces. It is not designed for floor installation or foot traffic, exterior or outdoor use, dryer exhaust venting or use as a filter-holding return grille. Confirm the airflow function against your HVAC layout before ordering. It suits office and commercial ceilings as well as residential rooms.

How to Measure for This Vent

Remove the existing vent and measure the width and height of the duct opening, not the outer face of the old cover. Match those two numbers to the nominal size above. The overall face measures 9-3/4"W X 9-3/4"H.

Installation

Position the square ceiling diffuser over the duct opening with the louvers facing the room. Confirm the frame sits flush against the ceiling surface before marking the screw points. Secure it with the included screws without overtightening, since excess force can distort the frame.

What's Included

• 1 x square ceiling diffuser
• Mounting screws

Ductwork, wall anchors, and installation tools are not included.

Care and Maintenance

Clean the square ceiling diffuser with a soft, damp cloth and mild soap. Avoid abrasive chemicals that can damage the white finish. Dry the surface to keep moisture off the metal.
