great info. Thanks for the research and comments. It didn't make any sense to me until I saw the diagrams.  greatly appreciated.

I have come across this kit that I can't find any information on. When I research the military part numbers it shows as being for use on some of the C130 variants. This is basically just a cable and pulley kit but there are some things that raise my curiosity factor. It is in a very nicely made box, It has steel cable with hooks, It has three heavy duty roller brackets that appear to be used to pass the cable around corners. But the two cable blocks appear to be very light duty. The hooks are lightweight and the pulleys appear to be made of a phenolic material so not much load capacity there. I asked at the local foresty service flight office and they thought it was used as an auxiliary cable for winching in pallets. And it certainly might be. But the light duty pulleys seemed strange and why have three corner roller brackets. So I'm curious if anyone knows for sure what this is for.
