Feeding Wire Through Insulated Wall

Feed cables through the holes.

Feeding wire through insulated wall.

If you need to fish a larger cable or bundle or if your buddy is going to feed the cable to you from above or below thread a pull cord through the bull nose. Run the free end of the cable to the next stud cavity location. Then pull the cable through the wall plate and out the next wall box opening. If the wall contains insulation try to fish the wire between the outer paper or plastic cover and the wall.

Be sure to leave enough slack on both ends to make connections. Push the tongue into the wall and feed it through until it appears at the other end. If you must fish wires through exterior walls the best tip is to avoid spinning the flex bit until you make solid contact with the wood you plan to. Support cables at 4 1 2 inch intervals with appropriate staples or clamps.

Here s where you can get piano wire. Connect the wire to the tongue by passing it through the hole in the end of the tongue and then folding it back on itself a little bit of electrical tape around the wire wouldn t hurt as there is nothing worse. The best advice for fishing wires through insulation is avoid it if you can the potential is always there to damage the vapor barrier or bunch up insulation leaving cold spots in the wall. Feed it up to the 3 by 5 inch hole at the top of the wall.

I ll be showing tricks to cut lots of time off fishing wires in walls. If you re fishing a small cable like a security cable you can attach the cable to the end of the rod by threading one of the wires in the cable through the hole in the bull nose. Make sure to use approved attachment methods drilling holes through joists or stapling the cable where required. Keep the fish tape against the inner edge of the drywall and out of the insulation as you feed it toward the upper hole.

Fishing wires through a wall can be tedious but in most cases you only need a couple of basic tools. If there is no cover press the wire against a stud and use it as a guide.
