So OK ... what I am thinking it is the inside offset sheaves that the wire does the real job on. They look to be 1/4 the size of the outside sheaves ... and it wouldn't take much for the steel wire to cut deep.

We have a local source currently with 5 of these boxes unused, which is the direction I opted to go.
