Okay, simple yet seemingly impossible question here... What type of terminal is this? It looks like exactly what we need, but I found the image on an advert for the shrink-wrap shown in the picture. The company don't know what it's called, none of the engineers I have asked have known, but if this terminal does what I believe it does (essentially 'lasso' a pole) it would save us SO much fabrication.
I have tried reverse image searches and googling every permutation of its description I can think of. Any help GREATLY appreciated!
