The hole sizes in Rohn 25 (and in Rohn 20) are 1/4" and
5/16" - they are NOT 3/16" & 1/4"...the factory-supplied
fasteners are 1/4-28 thread and 5/16-24 thread...

Subject: [Towertalk] Rohn 25G Questions
> I recently acquired a Rohn 25G Tower and I have a few questions for the list
members. BTW, It will be up approx. 60 ft. and I am in an 70mph county.
> Why are the holes on the section legs 2 different sizes? One is 3/16' and the
other is 1/4". Can I drill out the 3/16" holes and make them 1/4" like the rest
or should I leave well enough alone?
> I called an engineer at Rohn yesterday and he told me that he had no idea why
they did it that way. He said they were engineered in the 60's.
> Rohn's guy wire recommendations on a 60 ft. tower are one at 28 ft. and one at
45 ft., 48 ft. from the base. I only have about 39 ft. of space from the base.
Will this cause any problems?
> Last but not least, where can I buy Rohn accessories for a 25G? Guy wire
> I would appreciate any recommendations.
