I know of TWO towers that fell full length from cables pulling
through TWO cable clamps and heard of a third (120 footer)
where all but the BOTTOM set of guys pulled out just after
the tower was installed (no antennas yet).
My first introduction to guy grips was in the mid 1960's
by W1EVT who used them on his 19 R25 towers (140ft)
on a vacation trip to New England. I've been using them
on my own towers since 1975.
