Product Overview

The 30"W x 6"H brown steel triangle baseboard return grille carries return air back to the HVAC system through a baseboard opening. Powder-coated steel resists dents and rust for years of use, a stronger choice than lightweight plastic covers. The 1-way blade pattern directs air across the room. Select this triangle baseboard return 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 triangle baseboard return grille rigid during installation and resists warping over time.
  • Brown finish: The brown finish coordinates with common flooring, trim, and hardware.
  • 1-Way air pattern: The 1-way throw sends conditioned air where the space needs it.
  • Right-fit sizing: Ordered by duct opening size, this triangle baseboard return grille matches standard duct dimensions and cuts wrong-size returns.

Is This the Right Vent for Your Opening?

Choose this triangle baseboard return grille if you need a return-air vent for a baseboard opening. This triangle baseboard return grille carries return air and mounts on baseboard 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

Measure the open space between the baseboard and the floor where air passes, then match it to the 30"W x 6"H size above. Do not measure the outer flange. The overall face measures 31-3/4"W X 6-5/8"H.

Installation

Position the triangle baseboard return grille over the duct opening with the finished face facing the room. Confirm the frame sits flush against the baseboard 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 triangle baseboard return grille
  • Mounting screws

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

Care and Maintenance

Clean the triangle baseboard return 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.
