As long as the holes match up close enough you can use a thick stiff copper wire and run it down into the hole from the wall raising it up and down gently moving it left and right until you feel it go through the hole, then tie a strong. At the speakers, poke the wiring into the wall. Exit the drywall down at baseboard height. You will have to go strait up the wall into the attic craw space if there its one.
This gets tricky on outside walls because there is no room to drill a hole through that top plate to get into the attic and there should be insulation in the. Pull the cable through with a fish tape. Carefully extend the fish tape from one opening to the other. Tape the end of the fish tape tightly onto the cable with electrical tape. Make sure the tape is smooth so the cable is able to slide through the opening.
Then, retract the fish tape to pull the cable through. At the wall opening, carefully and steadily retract the fish tape, pulling the cable to the wall opening. In order to gain access to a wall cavity in order to fish an electrical wire into it, you must first choose the location you want to install the outlet.
Once locate mark the box opening on the wall between two studs. You may find it easy to do this with a stud finder. We will be using a cut-in box to add this device.
With the fish down the wall and fed out through the box opening, attach the free end of the wire to the hook on the fish and secure with tape (14). Slowly pull the fish and conduit up the wall until the conduit comes through the top. Once the conduit is through the wall , you can complete the installation. It’s really tempting to fish low-voltage wires (like coax and Cat-5e) through existing holes occupied by electrical cables, but don’t do it!
Even though cables are insulate the high-voltage current can interfere with the signal in the low-voltage wires. Fish tape is a springy steel tape that electricians use to pull wire through walls. Fish tapes are the best tool you can find for pushing through holes in a wall.
Some fish tapes have hooked ends to grab a second fish tape. Then, tightly wrap the electrical wire cable with electrical tape from the point that it is connected to the fish tape to just past where the other wires are bent back. Snake fish tape, a piece of thin steel wire designed to guide and retrieve wiring, through the light fixture hole in the ceiling toward the wall -to-ceiling access hole. It can get difficult to maneuver the more you use. It also gets a little more difficult to reel back in.
In fishing wires from the attic where the rafter meets the wall plate, you might have to work from outside the attic by removing a piece of the soffit, or work from underneath (if you’re not on a slab) by drilling through the bottom plate from a basement or crawlspace. 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. Push the rod to the same corner you used with the drill bit.
During sweltering Florida summers, temperatures in these spaces can climb to well over 130°F. This may be easier said than done, and it’s good to have a helper. In my experience, the “wire fish” tool is necessary… we tried a wire clothes-hanger, and it wouldn’t work.
Extend the fish stick so that it protrudes out of both the top and bottom holes and you can tape it to the wall temporarily. Feed the cable vertically through the hole to the box. It helps to straighten out a coat hanger, tape the cable to it and feed the coat hanger through the hole. The stiff coat hanger wire is easier to manipulate and catch than electrical cable. Tape the Wire or Pull String on the end and push the Rod through.
Insulation can be a real challenge sometimes. You can get a Egg Beater tip that pushes through insulation. Fish Tapes are designed for conduits.
Good place for tools and information on Wall Fishing is Labor Saving Devices. If we hit any snags, we’ll use this fish tape to help pull the cable or conduit on through. Now we’ll head across the wall , first with our electrical cable , then with the plastic conduit. We’ve got our wiring run and in place.
It's a stiff metal ribbon on a reel that's pushed thru the cavity. Electricians use a tool called a fish tape. After you successfully get the fish tape through to the remote en you attach the wire onto it and pull it back through.
The idea is to drop this magnet behind the wall , and use a second magnet to fish it through to where the cable needs to go. Whether sticking the magnet into the wall from above in the attic, or from below in the basement, the idea is the same. Fishing a wire from the attic to the basement, without cutting a hole in the wall makes for more of a challenge though. I suppose a solution would have been to just install an extra electrical outlet in the hallway, just to have an excuse to cut another hole in the wall and avoid a difficult wire fishing job. Before we begin, I want to note that it is against code to run a power cable through the wall so that it plugs into the tv on one end and an electrical socket on the other.
To meet code, you should have an outlet installed behind the TV so the power plugs in directly without cords running through the wall. The problem is that one wall is an exterior wall that contains fire blocks and insulation. As long as the joists run perpendicular to the wall in which the switch is you should be able to do it.
Having cut a hole in the wall , you can feed the drill bit up and drill through the top plate of the wall. The tough part is grabbing the wire through the hole you drill in the top.
