Which type of fittings are nicopress and which ones are swaged?
I have seen an integral piece that has a loop and a compression area that a
wire goes directly into as well as two looped wire endings.

The loop goes around a small V with a circle at the top, and then the two
wires get clamped together somehow. One clamp type is a lead piece that
gets squished by a tool, the other is a U shaped bolt, with a small
platform and two nuts to squeeze it. What are the problems/names of the
various methods, how much tension can each handle, and how does one do each
one properly?

Thanks,
Bill.
