I'm needing to run an ethernet cable from my home office thru the attic to the living room at the other end of the house... problem it that is is an older house that has one of those really low roof lines so there's hardly any room at all to crawl thru the attic to do this normally. But, in the closet I do have a trap door so I can stick my head up in the attic and see right down to where I need to run the ethernet cable to. So, is there some sort of retractable tool that is available to would extend out about 60 or 70 feet that would enable me to tie the cable on to so I can drag this down the length of my attic without having to hire some little kid to crawl thru there to bring the cable down to the other end? Any ideas (other than running it on the outside which isn't going to happen) on how to get the cable down there without having to crawl thru this very low attic space would be appreciated. .
