I've been following this thread and most of the answers you got were either
flat wrong or based on some anecdotal info that clearly exceeds the
manufacturer's specs. And the examples you cited above are downright
DANGEROUS.
What're you NUTS or something for climbing them?!?
There is a pamphlet and the info is also in the Rohn catalog. For the
most part, you can go 14 feet above a housebracket but freestanding specs
depend on the load and the windspeed.
You can get a Rohn catalog on CD - a highly recommended addition to your
tower library - from _www.rohnnet.com_ (http://www.rohnnet.com) . They'll
send it to you for free.
The same info is on the website and you can look it up.
The bottom line is that freestanding Rohn 25g, etc. are rated a LOT LESS
than you think. And ALWAYS follow the LXC Prime Directive to "DO what the
manufacturer says".
