Wire fishing trick that cut my install time in half
I was pulling cable through a finished wall for a panel upgrade in a condo near the coast and kept snagging on insulation every other run. After the third stuck pull, I taped a small neodymium magnet to the end of my fish tape and used a second magnet on the outside to guide it past the trouble spots. Anyone else use magnets this way, or do you have a better method for navigating insulated walls?
The magnet bit got me laughing because my first thought was here comes another guy trying to sound smart. Then I remembered I spent two hours last month cursing at a wall while my tape kept popping out of the top plate hole. So yeah, no room to talk.
Magnets on fish tape work but only if the wall is empty enough for the magnet to drag. Packed insulation and you're just fighting two forces instead of one. My go to is a chain bead on the end, it drops and rolls past most snags, then I hook it from the box with a magnet or a bent coat hanger. Worth trying when the neodymium trick stalls out.
