Product Overview

The 16"W x 10"H white steel supply register carries supply air into the room through a ceiling and sidewall 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 supply 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 supply register rigid during installation and resists warping over time.
  • White finish: The white finish coordinates with common flooring, trim, and hardware.
  • Adjustable airflow: The built-in back damper controls the volume of air (from fully open to closed), so you can set airflow from a gentle breeze to a full flow. Where the register has adjustable blades, they deflect the throw left or right to aim the air.
  • Right-fit sizing: Ordered by duct opening size, this supply register matches standard duct dimensions and cuts wrong-size returns.

Is This the Right Vent for Your Opening?

Choose this supply register if you need an adjustable supply-air vent for a ceiling or sidewall opening. This supply register carries supply air and mounts on ceiling and sidewall surfaces. It is not designed for floor installation or foot traffic, 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 17-3/4"W X 11-3/4"H.

Installation

Position the supply register over the duct opening with the louvers 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 supply register
  • Mounting screws

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

Care and Maintenance

Clean the supply register 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.
