I believe there were split crimps, galvanized, that were supposed to be
put around the free end of the big grip. I have several towers put up in
1992 that didn't use them and have survived Mother Nature without
problem. However that doesn't mean it should not have had them installed.

When I put up my tower in 1989, I used 3/16" EHS and big grips. At the
time, I don't think anything was normally placed at the end of the big
grip. Just to be safe, I put a 3/8 inch cable clamp at the end of each
one. That seems to have worked fine. Now I'm replacing the tower,
using the same size EHS and big grips, but I'm seeing inconsistent
references to using "end sleeves". I can't, however, find any explicit
instructions calling for their use. By contrast, the instructions for
installing the big grips on Phillystran specifically call for
installation of a nylon cable tie. (I can see why it might be bad to
compress Phillystran with a cable clamp.)
So my question is: Are the end sleeves mandatory, and, if so, can I
use cable clamps instead. One obvious disadvantage of the cable clamps
is the things can get snagged on them. (Been there, done that.)
FWIW, this time around I'm using Phillystran for the center part of
each guy, with a short length of EHS at the tower end and a longer one
near the ground. I don't think big grips were available for
Phillystran in 1989.
Thanks and 73,
