Product Overview

The 3"W x 10"H brown steel floor register carries supply air into the room through a floor opening. Powder-coated steel resists dents and rust for years of use, a stronger choice than lightweight plastic covers. A built-in damper adjusts or shuts the airflow, so comfort can be set room by room. Select this floor register 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 floor register rigid during installation and resists warping over time.
  • Brown finish: The brown finish coordinates with common flooring, trim, and hardware.
  • Adjustable airflow: The built-in damper controls the volume of air (open to closed).
  • Walkable strength: The reinforced core supports foot traffic, which suits floor openings in busy rooms.
  • Right-fit sizing: Ordered by duct opening size, this floor register matches standard duct dimensions and cuts wrong-size returns.

Is This the Right Vent for Your Opening?

Choose this floor register if you need an adjustable supply-air vent for a floor opening. This floor register carries supply air and mounts on 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 4-3/4"W X 11-1/2"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 floor register

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

Care and Maintenance

Clean the floor register 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.
