Rohn 25 legs are 1.250 od 16GA and 20 is 1.250 18 GA. the lattice material on
25 is 5/16 solid rod and 20 is 9/32 and the biggest visual difference is Rohn
25 has 15 3/4 between horizontal cross braces as compared to Rohn 20's 18 1/4
distance. resulting in 8 cross braces per 10' foot straight section of #25 and
only 7 on #20.
