Technical Data

Product Overview

The 18"W x 18"H white steel return air grille carries return air back to the HVAC system through a ceiling and sidewall opening. Powder-coated steel resists dents and rust for years of use, a stronger choice than lightweight plastic covers. Select this return air grille by its duct opening size, not the overall face size, so it seats correctly on the first fit.

Key Features

Steel construction: Steel keeps the return air grille rigid during installation and resists warping over time.
White finish: The white finish coordinates with common flooring, trim, and hardware.
Right-fit sizing: Ordered by duct opening size, this return air grille matches standard duct dimensions and cuts wrong-size returns.

Is This the Right Vent for Your Opening?

Choose this return air grille if you need a return-air vent for a ceiling or sidewall opening. This return air grille carries return air and mounts on ceiling and sidewall surfaces. It is not designed for floor installation or foot traffic, exterior or outdoor use or dryer exhaust venting. 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 19-3/4"W X 19-3/4"H.

Installation

Position the return air grille over the duct opening with the finished 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 return air grille
Mounting screws

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

Care and Maintenance

Clean the return air grille 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.
