You guys ever use these? How do you crimp them? On the back it states to crimp them using a GCP-5000A, which is nearly impossible to find seems like. I have the tool finally after talking with GB about it a bit, and this is what they look like crimped properly, never seen that in the field, thats for sure.

Yes,I'am familiar with those but, the application I use them for is completely different. Those are known as wire termination ferrules. When I am prepairing wire to connect to a wiring block, I'll strip back the insulation and slide a ferrule over the loose strands and crimp the ferrule. This keeps the stray wires together when tightening the set screw, preventing wire damage. Open barrel ferrules crimped onto loose stranded wires is required in the Aviation industry. I was replacing a light switch in my neighbors home once and noticed the ground wires were connected together using those wire ferrules. I've never seen open barrel ferrules used like that...lol
