In reply to Aigen:
I know it's all down to personal preference but the best racking krab for wires for me is the Stubai Easyclip. It's not got a wire gate, but the gate has the notch, not the nose, so wires never get hung up. I've never dropped a wire in 20 years of using them. I used someone else's wires recently and dropped a couple just up pitch two because they got hung in the gate.
There's some on an auction site at the moment as part of a quickdraw. I'd buy 'em up and bin the tapes and other krabs just for the Easyclips. Awesome.
