Does the Kobayashi Maru specify specific euro style load rated snap hook with screw lock and wire rope size of the safety cable to use? Or in general, just use 1/16" to 3/16" sized, 36" vinyl coated safety cable considered safe? This safety cable length - only being 6" longer than a common non-coated safety cable... what's the point? Why vinyl coated as opposed to other coatings if at all and that length in making it possible for more safety in doing so?
