There are clamps similar to those that have been described here
known as "Crosby clips," and in my catalog (Alloy Sling Chain,
Chicago, IL), on the next page there are similar clamps called
"malleable wire rope clips." It is unclear to me what the
differences are, and I wish someone more knowledgable than me (which
would be almost anybody) would jump in with some of these answers.
Interestingly, there are torque values posted for those clamps, but I
would be willing to bet a pizza (if there's any left) that no ham has
ever put a torque wrench on their guy clamps.

My wife keeps asking questions like, "how do you KNOW that?" I have
been blessed (cursed) with an astonishing memory for minutiae. Some
of it I read, some I've learned the hard way, some I've applied from
readings or experience in other areas (my answer on wire rope and
deformation is an example. My experienc there is mainly with hemp
rope from Scouts, rock climbing, tower work, etc.). The problem is,
while I might be able to tell you how to do something, I can't
necessarily prove it.

There is a lot of truth in that.

I am very nervous about using stainless steel anywhere significant
(a relative term) torque is required (because of the ease of galling
the threads), or where the natural plasticity of the material is
required to keep things tight. Please, some metallurgist jump in

Actually, I've never had any of the stuff up long enough for it to
become either a repair or replace issue. I converted to Phillystran
some time ago and never looked back. I got in in the potted ends
period, didn't do anything through the Crosby clip days, and now that
they have Big Grips available, my next Phillystran installation will
