The Hazer wsa purchased by Glen martin Engineering in the early 1980's.
They used to make
versions for the 25G, 45G, Glen martin towers, and a version that you
defined and could go around any tower. They dropped all but the Rohn and
GME versions but am unsure if they have a version that
goes more than 70 feet.
Suggest you go to the Glen martin Engineering web page plus ask if special
versions are available.
I have been involved in two versions of the 25G version and you have to
remove guys which is scary
