I found another tower that I can have if I take it down. this tower is on a 3 1/2 story building and I am guessing it is over 50-60 ft. and attached to building in two places,top and center.

Now If it`s rohn 25 I will take the time to get it but if it`s 20 I dont want it.

How can I tell which it is or is there no way?

Thanks,
AP

Measure the steps.
The 25G is 12-1/2 inch equilateral triangle design, with continuous zig-zag cross bracing, is electronically welded. The heavy duty 1-1/4 inch steel tubing side rails, continuous solid rod bracing, and eight zig-zag braces per 10 foot section create.



Hope this helps

Here is another way to tell the differents between 20g and 25g

The only way that the
average person can tell the difference is the weight. Rohn 20G weighs
32 pounds per section and the 25G weighs 40 pounds. I realize that most
people can not tell the difference between 32 and 40 pounds without a
scale, but with this knowledge something could be improvised. The
reason for the weight differences are the solid rods on the 20G are 9/32
diameter and the rods on the 25G are 5/16 and the tubing side rails are
18 gage and 16 gage respectively.

Hope This Helps Too

one more thing I forgot..
and the eaiest way to tell
20g steps are 18" apart.
25g steps are 12 1/2" apart.

Hope this helps.
