KoldLok 6" Round Brush Grommet, Large Split Grommet with Brush, Raised Floor Airflow Management 1 Pack

I'm using this in my home on a wall instead of the floor of a data center. I used a jigsaw to cut away the protruding edges on the back as I already had an expensive 5.5" hole saw (too small for the 6" hole the edges would've required) and just had a need to cover the hole neatly. Works great for my purpose. I was going to buy directly from the manufacturer, but they were out of stock and were nice enough to lead me to their product here on Amazon. Thanks!

This grommet is a little costly for what it is (a small piece of plastic) but it is very convenient and there's no alternative in it's class. It makes your work look great when installed with a little help of a cable comb (see before and after photos).

I us this for my generator enclosure and it allows me to feed my large generator cable thru and keep everything dry inside.This is sturdy and well made took 3 minutes to cut a hole and screw it in.I can verify it will allow a 30amp connector to pass thru as well I can put several 20amp cords also if needed.

This product was good looking and easy to install. It included screws, and has both the brush and a rubber lip to help with cable management. Easy to line up, and very secure once installed.

Disgustingly expensive for a hunk of plastic; definitely wouldn't spend my own money on this particular item, but at least the quality is there. -2 stars due to the price.

It works great. solid construction and nice fit. Used as a cover for 6" PVC conduit in a floor.

Works great to seal out critters.

You would think for the price for a piece of plastic they would include screws. They didn’t.
