I have power that runs from my house to my garage, that was installed when I moved here. It's run overhead and is secured to a metal wire attached to the side of the house and the garage. The cable has been secured to the metal wire with zip ties but they are starting to fail. It's too high in the middle for me to reach with a ladder. Is there a telescopic tool available to secure two wires together? Or is there another solution other than buying a big A frame ladder?
