We've got two Rittal black 42U server racks but they never came with any additional cable management and as such any cables that need to run round the side or back of the rack aren't the neatest in the world.

As I'm going to have to shift some servers about in the not too distant future to make space for the new virtual hosts I thought it might be worth trying to tidy it up a bit.

We've got cable management loops like these...

Was just wondering if there's any extra bits we can get for the sides? I'm mainly thinking for the CAT6 cables coming from the front of our core switch and running round the back of the servers.
