Review: Brush Plate Used in Ceiling - Used this as ceiling passthrough for 24 cables. Plenty of room for another 24 cables at least! The back side of the brushes has a nice rubber piece that helps keep air and debris from passing through. Is exactly what I needed/wanted to route home runs through ceiling into my network rack.
Review: Works as advertised - Works as advertised. Needed this to feed my cables through the ceiling into my 25’ conduit run. Does the job. I asked a lot more out of it. Just beware - if you plan on doing what I did and have it go into PVC pipe on the other end, the other side of grommet panel is not round but oval. I made it work though. Just make sure you have anchors when drilling into drywall.
