In Donovans book section 3 page 32 (Rigging 101), it has a few lines about adding a steel cables as a fire safety on ploy spansets.   Then it goes on to point out that there doesn’t seem to be any use in this practice bc the steel will break under similar heat that melts the poly.    So why do we all put a fire safety on a poly spanset ?  (I know I do)

The new “gak flex” is steel cable inside, so as standard practice we don’t add a steel cable.    Are we setting ourselves up for failure?

I have seen spansets melt from the heat of a down can (and a delay speaker fell from it).   I still don’t think that heat would have damaged a gack flex.

Someone has got to have tested this.
