Why Buy A T-Bar Return Grille?

You may think of grilles and registers as a generic component of the ventilation system, but they are the most visible representation of your air system. Made for easy drop ceiling installation, this grille provides easy access to replace the filter. Every part is hand inspected for quality assurance before it's packaged. Then, it's carefully shrink wrapped with a cardboard backing to prevent damage in shipment.

Screws Are Included.

How To Measure A Grille

Overall Size

Measure the size of the duct opening. Do not measure the old vent cover. If your duct opening is 14" wide by 20" tall, order a 14x20

Height vs. Width

The first number in a grille size represents the width, the second number represents the height.
