6 Inch Round Grommet

Fill cutouts in raised floors with RLE’s grommets and see an immediate improvement in airflow and efficiency.

Why Should You Use Grommets?

Plugging holes is one of the easiest ways to improve airflow and efficiency in any raised floor environment. If air can escape through holes in a raised floor you limit the effectiveness of containment and decrease your cooling efficiency.


RLE’s patent pending fire rated foam grommets seal cutouts in raised floors and show an immediate efficiency return.

What Sets RLE’s Grommets Apart?

Our foam grommet seals better and prevents air from passing through the grommet significantly better than the leading competitor’s grommet. How much better? When tested against the leading competitor, 50% LESS air escaped the RLE grommets. Drop in an RLE grommet instead of a competitor’s grommet and see an immediate improvement in air loss.

Made With Your Convenience In Mind

Our foam grommets split quickly and easily into two parts. This means you can use our split integral grommets whole or quickly split them into halves for installation around existing cables or pipes, or against a flat edge. Four screws provided to ensure a secure installation.

RLE grommets are flame rated to meet facility safety requirements, and our patent pending design is a testament to our commitment to innovation and ensures you receive the quality and reliability you expect from all RLE products.

Stocked And Ready To Ship In ANY Quantity

We understand each facility has its own unique efficiency goals and budgetary parameters. We want you to be able to leverage grommets at any time, so you can purchase one RLE grommet or several grommets at a time. Whether you need one grommet or a box full, we’re happy to help.

Our grommets are stocked and ready to ship from our manufacturing facility in Fort Collins, Colorado.
