This seems to take a fishing system to extremes. Maybe call in the electrician and let them fish or pull it for you.
We recently moved into a new home, which has existing recessed cable plates, similar to the ones here: http://www.garvinindustries.com/low-voltage/cable-splash-wallplates/cable-splash-nose-plates/lvp1np?gclid=CjwKEAjw7YWrBRCThIyogcGymQsSJAAmz_ndF-k17Dz15sOKZKR8dWMs1p4hWoVYa35ZamLIKUG3dxoCrLrw_wcB. I have removed the front plate but have been unable to thread my wires through the wall. Is there an easier way to do this? Thanks so much for the help!
