This is a very nice Cat-5 adaptor, but it's a bit expensive if you need to use more than a couple. Be careful, once installed, the rear PCB can be pulled off the external krone housing, severing the solder connections, dropping it to less than gigabit speed, or worse, causing it to fail altogether. Basically, it's a weaker connection on the internal side, were tight internal cabling can pull too much, if there is not much play. Includes self tapping screws (appears to be the only Neutrik connector that includes them).
There are good accessories for this, a external cap door cover, and colour plastic labels.
