Raised Floor Airflow Management 4" Round Floor Brush Grommet (1 Pack)

Great protective barrier to keep dust, large insects and small rodents out. Good value, does what it's suppose to do, looks great and is durabile. Wasn't hard to install, took a few minutes. Buy it.

Perfect cover. Good quality and fit perfectly in my opening

Looks just like the picture and worked great.

It worked for what I wanted and I’m sure no one will notice it isn’t perfectly flush to the opening but I do. Possibly because it was so expensive for what I used it for, but that isn’t the products fault. Cant wait to get some cable hiders. Next time I need to move wires for my security system I’ll hire a contractor.

Just wanted to give a heads up on the color mainly. Excellent grommet, that can be modified as well. I cut the knockout fitting piece so it can be used flush, instead of into a hole in the wall or floor.

I bought this for its intended purpose and could not be more thrilled with the outcome. Having an area with plaster ceilings caused a bit of plaster breakage around the grommet. That's not a problem with this unit. Just be careful if you're cutting a hole. I used a hole saw, but in a 60-year-old home, things can end up not as intended. I am well accustomed with that. I am super pleased with this and will, buy it again should the need arise. I would love to see a smaller version in the 2" range for other projects I have.

I had to bring 8 wires up from the basement coming from my security cameras. This grommet worked great for this purpose. The rubber and brush seal is perfect for keeping insects and air from coming up from the basement, without putting too much pressure against the wires. I am very pleased with this item.

Perfect for my needs where the wire was already in place because of the split design I can put this around the existing wire and it seems to be strong and secure.
