! Instructions for easy threading of the cable!

Once here, some people reported the difficulty of threading the cable, I had almost decided against the rack.
But you could just send them back, I ordered a couple that Amazon really delivered super fast.

To thread the cable:
I have a 2x2.5mm thick cable threaded (from the usual with transparent sheath) per rack in less than five minutes, so it was not so bad by far, as shown here on several occasions.

1. Measure cable and cut rather too long than too short, possibly turning wires together and possibly taping them
2. The threading on the thread of the curved piece start, turning the cable constantly and push - with a narrow pliers the cable from the lateral hole pull, from where it goes to the box later
3. Slide the long piece of cable at the bottom of the bent tube into the next tube, then screw it with the lower tube and continue pushing
Attach and wire 4. Box before connecting the amplifier
5. Done!

I hope this helps a few people who might otherwise unnecessary difficulties with the stripping drawing - anything but the quality of the stand has been described several times.
Incidentally, I like the rough surface better than this whole piano-hype, in which you can see every speck of dust and every fingerprint!
