Product Overview

The 10"W x 30"H brown steel return air floor grille carries return air back to the HVAC system through a floor opening. Powder-coated steel resists dents and rust for years of use, a stronger choice than lightweight plastic covers. Select this return air floor 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 floor grille rigid during installation and resists warping over time.
  • Brown finish: The brown finish coordinates with common flooring, trim, and hardware.
  • Walkable strength: The reinforced core supports foot traffic, which suits floor openings in busy rooms.
  • Right-fit sizing: Ordered by duct opening size, this return air floor grille matches standard duct dimensions and cuts wrong-size returns.

Is This the Right Vent for Your Opening?

Choose this return air floor grille if you need a return-air vent for a floor opening. This return air floor grille carries return air and mounts on floor surfaces. It is not designed for exterior or outdoor use or dryer exhaust venting. Confirm the airflow function against your HVAC layout before ordering. This heavy-duty return floor register holds up to foot traffic in busy 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 11-3/4"W X 31-3/4"H.

Installation

Set the floor register into the floor opening so the face rests level with the floor. No screws are required; the register drops in and its flange keeps it seated. Lift it out by the face for cleaning whenever needed.

What's Included

  • 1 x return air floor grille

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

Care and Maintenance

Clean the return air floor grille with a soft, damp cloth and mild soap. Avoid abrasive chemicals that can damage the brown finish. Dry the surface to keep moisture off the metal.
