Ferrule for triple solid core CPC in socket w/metal back box

Ancillary to my other post, I wanted to check if something was up to standard in part of the installation I'm doing.

We have a metal back box in this case. I've got a fly lead going to the face plate, which has the two other CPC cables going to it also.

I decided to use a ferrule to connect the triple CPC together and then insert in the faceplate terminal. I'm just not sure about crimped ferrules on solid core cable. It seems to be rock solid, but wanted to check I've not erred.

The tool used was a pair of knipex self adjusting crimping pliers:
