8"x4" White Aluminum Linear 2-Slot Diffuser, Slim Modern AC Vent Cover for Wall, Ceiling & Floor

Product Overview

The 8"W x 4"H white aluminum linear slot diffuser carries supply air into the room through a ceiling, sidewall and floor opening. Extruded aluminum resists rust in humid rooms, a stronger choice than lightweight plastic covers. The 2-slot face spreads air in a clean, continuous line. Select this linear slot 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 linear slot diffuser rigid during installation and resists warping over time.
• White finish: The white finish coordinates with common flooring, trim, and hardware.
• 2-slot face: The 2-slot opening gives a slim architectural look while moving air evenly.
• Right-fit sizing: Ordered by duct opening size, this linear slot diffuser matches standard duct dimensions and cuts wrong-size returns.

Dimensions and Specifications

Is This the Right Vent for Your Opening?

Choose this linear slot diffuser if you need a supply-air vent for a ceiling opening. This linear slot diffuser carries supply air and mounts on ceiling, sidewall and floor surfaces. It is not designed for 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.

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 9-13/16"W X 5-7/8"H.

Installation

Position the linear slot diffuser over the duct opening with the slotted face 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 linear slot diffuser
• Mounting screws

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

Care and Maintenance

Clean the linear slot 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.
