I bought this socket with rubber connector, as I had no desire for self-made that you can hang behind a UPS. What are my very good like the mounted at a 45 ° angle sockets, so you can use it without problems almost every type of plug, without this being another male in the way, what in computer systems is usually very important because here often 90 ° angled connector be used in the normal outlets arranged mutually then block. Unfortunately, this power strip is actually intended for installation in a rack and not to order without this rack shelf. In addition, the cable with 3 meters for most is probably too long, and here you can choose any other way. So we have one star deduction.
Conclusion: If you want to install this power strip in a rack, or it does not bother that the holders of these are available, for this bar highly recommended.
