I am planning on useing in rigging a safety line
...
I searched also for the "lock jack" tool ...



hi Bertie,

google for "lockjack" as one word (narrowed down with "arborist" or
something like that)

my tip: feed a line over the roof, inside the house and attach it to
the stairs ( I mean: attach to something more rigid than a chimney )
