Never see it , never installed, never used, but that system is used in self
support metal poles , self support towers ( big commercial towers) recommended
in Trylon and AN Wireles to mention some of the ones in the ham market
My personal opinion is adding that cable will make difficult to move in the
tower, a professional climber will be 100% the time attach to the tower
with lanyard or fall arrest system (or both) during climbing, working and
descending for that reason in this type of tower is an accessory that will
make more problem to work , but will say in ROHN 80 YES, add that safety
cable to make the climbing and descending safer.

Has anyone installed or have experience with a Gemtor Series 5000 or 6000
Ladder Safety System installed on a tower like a Rohn 45 or 55? This is a
"Ladder Climber's Safety System" which uses a sleeve (e.g. Gemtor Model
#VW655) on a vertical cable which automatically follows the ascending and
descending movements of a climber on a vertical ladder. The sleeve attaches
to the front safety ring on a whole body harness. If a slip or fall occurs
a locking mechanism engages and limits the fall to a few inches.
It is also called a "vertical wire rope grab".
