The installation of the case requires a little planning, you can not open the case if we plunge to a difficult location. The case closes with 2 screws on each side. It attaches to the wall but the 2 fixing screws do not go through the holes so you need to find 2 smaller or fix permanently in the disassembling.
2 cap screws to the one I have received are damaged, the threads are worn out impossible to get them out without bending a little pokey, too bad.
That said, this patch panel is the best I've found at this price.
Concerning the most important shipping costs than other distributors (in 2012), they are quickly forgotten if you order a batch of patches, connectors, cables and other tools at the distributor.
