rope grabbers I've seen so far are only for rope, not wire. How about
Phillystran?
Not PhillyStran either - the PVC jacket is too soft and prone to
abrasion damage plus there's no grab/slider for it. All the tower safety climb
systems I've seen use 3/8" wire rope (with the exception of the Trylon safety
rail
system). The best sliders are the Rohn and DBI/Sala ones.
I've never seen one on an amateur installation - too expensive and if
you observe the 100% tie-off to the tower, you really don't need it anyway.
Cheers & climb safely,
