There is not a lot you can say about a 2U rack panel, but I will have a go.
One major thing (I think is major) is that the end of the strip top and bottom is bent over at 90 degrees with makes this a very stiff and strong panel, especially when combined wit the fact that is it a quite heavy gauge steel it is pressed from. Many rack strips have no bent edge which makes them flex and this starts to make the paint crack, so no problem with this one.
Once fitted int the rack, it is rock solid. I would also have no problems in drilling into this strip for fitting plug sockets etc.
