Product Overview

The 6"W x 4"H white aluminum linear bar grille carries return air back to the HVAC system through a ceiling and sidewall opening. Extruded aluminum resists rust in humid rooms, a stronger choice than lightweight plastic covers. Select this linear bar grille 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 bar 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 linear bar grille matches standard duct dimensions and cuts wrong-size returns.

Is This the Right Vent for Your Opening?

Choose this linear bar grille if you need a return-air vent for a ceiling or sidewall opening. This linear bar 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 7-13/16"W X 5-13/16"H.

Installation

Position the linear bar grille over the duct opening with the bar 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 bar grille
  • Mounting screws

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

Care and Maintenance

Clean the linear bar 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.
