Thomann V2020 Grey 10 Pack

Absolutely amazing product to keep your cables in order.

These ones are designed so that they have a very wide range of diamaters at which they can properly lock. You could use the same strap to fasten up to 9 meters of cable rolled up around 4 fingers (more length if you roll the cable in a wider circle), down to the diameter of a pinky finger or even a single strand of cable.

By comparison, I recently tried cable straps from a DIFFERENT brand and they had a very low range of diameters at which they can lock. I bought two sizes, the small one was too small for any decently sized cable, and the other one was too large for most cable rolls I was fastening and so the two velcro straps would not fall on each other to attach.

But these ones are very versatile, even when I've been using then "wrong" (just a normal loop around the cables, rather than slipping it in inside out then pulling to tighten, look at the instruction picture on the black version).

The black ones seem to be the universal favorite, but with these gray ones it's easier to tell at a glance where the tie is (for non-gray cables, anyway).
