Hi Bill,
I have seen some real problems too but they have lots of uses beyond
just supporting wires.
Thanks,

Folks,
I'm a bit sour on SS ties. These are easy to overtighten and have
caused
numerous ground faults in the field. My recommendation is to use
UV-resistant black wire ties and install 2-3 times as many as
necessary.
Sure some will fail over time, but we are much less likely to have
ground
faults, and proper O&M says that we maintain the wire supports over
time and
replace broken ties as need. Proper tension is a must and people
have to be
shown how to do it properly and checked up on in the field to make
sure they
are not getting them too tight.
Bill.

To tighten: 1. Pull tie snug by hand. 2. Cut tail about 20 mm from
clasp. 3. Roll tail with needle-nose pliers, like a sardine can
lid. This
tightens tie and hides sharp end.

Do not over-tighten to avoid wire damage.

For those that haven't used these before, beware that it is
difficult to
tighten them.
