Hi all,

I don't want to be critical of anyone, but am I getting correctly the sense
that installation protocols for R25, if they don't already, should stipulate
interim guys at intervals less than 30 feet?

It would certainly be a sphincter-testing moment for me to be swaying above
the ground at 60 feet.

This is certainly a good indication of Rohn 25's capacity free-standing
(read: little to none (which is within design parameters, I might add)).

73, kelly
