RackPath 1U Blank Rack Mount Panel Spacer with Venting for 19in Server Rack Enclosure or Network Cabinet – 2 Pack, Black

These are rolled on both top and bottom, which is the single best quality identifier I can think of for something static made out of metal. A flat plate would be easy to warp or bend if treated improperly. These will keep their shape well and look good in the process.

These panels helps me to cover the empty space in my rack. To be honest, I did not expect them to be of such a good quality. The fit and finish is almost as good as Mid-Atlantic and Navepoint. Will buy more in other RU sizes.

Using this on top of the shame shelf that includes my ISP router and modem. They work well and hides those ugly pieces of equipment while making sure they can still breathe. Theyre a bit thin but since theyre just spacers its fine.

I got everything as expected!
