Don’t worry. Thousands (millions?) of them are out there.
I had a tower go down decades ago due to improperly installed cable clamps (my
fault). Deadends are faster, easier, more reliable. I’ll never go back.

Subject: [TowerTalk] My first introduction to guy-wire dead end grips
I'm trying to understand the use of pre-formed wire-wrap dead-ends for
guy-wires.
If I understand the install process, the guy-wire itself doesn't wrap
around the lower anchor fixture.
But the dead-end goes into the lower anchor fixture and the dead-end
then wraps around the guy-wire.
First the guy-wire tension is pulled up to pre-tensioned position.
Then the dead-end is fed through the anchor fixture.
Then one leg of the dead-end is wrapped around the guy-wire...either
wrapped all the way or part way.
Then the other leg of the dead-end is wrapped.
And then the wrapping is complete....I think that approximates the
installation steps.
The question I have is, what is supposed to keep that wrapped dead-end
from slipping off the guy-wire?
Hard for me to believe it will grip the guy-wire just being wrapped
around it, especially when the guy wire is fully tensioned.
Why not put forged guy-wire clamps around the dead-end after its wrapped
to ensure it won't slip off the guy-wire?
What am I missing?
Also, companies like Hubbell and AED manufacture straight-type bolt-on
clamps that come in different lengths....like 6 inches with 3 bolts.
How does the bolt-on clamp assembly compare to the dead-end, in terms of
reliability and pull strength?
Thanks!
