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.

Good fit and finish along with excellent quality workmanship. Didnt need 2 pieces but now I have a spare in case I need it.

I was looking for a way to clean up my wall-mounted rack and make it look more professional. A vanity project, I know.

The RackPath blanks are a nice way to clean up the look of your rack mount setup and still allow for good airflow. The covers are made of a good thick metal and are not flimsy but have lots of holes allowing for air to pass through. The cage nuts fit as expected and the screws are included along with the M6 plastic washers.
