Dropping a weighted string down turned out to be really easy. I just taped the string to the cable and pulled it through.

I did manage to kink the cat6 cable and give it a tug. Is it likely ok or damaged? I guess the electrician will test it and work it out anyway.

Under house = dirty and dusty and cat pee smells = not fun.

Oh and here's the image of the conduit and such under the house. I pulled the smaller/lower one out so I could get my cat6 out.
