Having something like this fabricated sounds risky. Even with the standard
Rohn part (speaking of Rohn 25 with which I'm familiar), one weld, where
the bar attaches to the tube, stands between you and disaster. Welds are
notoriously vulnerable to fatigue, and even though there appears to be no
history of these failing, your weldor could have had a bad day.
Big Don does not trust the Rohn part. All my torque bars have an
additional safety loop of guy cable which goes thru the hole at the end
where the guy attaches, and around the corresponding tower leg above the
torque arm bracket. That way, if the weld in the torque bar lets go, at
least something is there to back it up.
