CONS: Item is to tall for a 4u space won't allow for other items to be directly above or below it without a small gap and also holes are to far apart and do not align properly. Needs modification to fit.
I purchased several of these blank panels in 1U, 2U, and 3U sizes. The panels themselves a very study and have a nice finish but all of the panels are too tall and require modification to fit. You can't even fit two panes together without modifying the holes or bending the lip on the top or bottom edge over. I can't recommend these panels.
