Mike,
I'm posting this to the reflector also, we just had a local farmer find out
the hard way on his grain bins.
Those critters are called "automatics" ( real name: strandvise clamp) and
are available at all good utility suppliers........well maybe not in Russia
though I'm lead to believe they use the same stuff we do here.
Reliable part #R5100 for 1/4" EHS.
Word of warning: All "automatics" are designed for tension applications.
If they go slack they have a nasty habit of letting the guy slip out.
Preforms stay attached even if they go slack. I'd stay away from automatics
for that reason in tower apps.
To remove the guy from your used automatic, get a blade screwdrive and
insert it in the slot on the side of the aluminum body. Push the wire into
the body towards the bail (just like you would if you were installing it
new) until the jaws release. The wire should pull back out easily.
Word of warning #2: NEVER EVER EVER re-use an automatic. You can not be
sure if the jaws have been damaged, mis-aligned or full of dirt. Any of
these conditions and a few more will lessen the holding power. That's one
of the reasons why they were still on the wire.
