As others have stated Lots of lube, more lube Use pull string to pull in a pull rope to pull the bundle The person that feed needs to keep them organized as they enter the conduit. Add More lube Add another cat6 for future Pull We recommend 3 2" minimum now. 1 for electrician 1 for you 1 for the stuff no one thought about. 1" PVC, 14/4db, 16/4db, rg6db, 3 cat6db

I like the idea of using the 10foot piece of conduit with 2 90º bends.
But also make sure that the coax is NOT the quad-shielding. And also, test this on the 100foot piece, see if you can pull all of your cable out on the yard the 100 feet first. Then attach the free end to something sturdy enough that you can pull on it. And twist all of the cables together as you use electrical tape in the opposite direction. Leave some space between each tape pieces, as this will give you enough flex to make the bends. Try to keep the cabling in the same order to avoid any over lap.
Yes, this maybe a couple person job. But it could be worth it.

You asked for how to do it, so let me tell you what I do when I have a mess like that. Take a piece of cloth, sock, whatever and use that to pre-lube the pipe. Use lots, and I mean lots of lube. Like 2-3 32oz bottles. Lube is cheap compared to stress you'll have if you get stuck. [Link: homedepot.com]If you use nylon pull-string, be CAREFUL. Unless you use EMT, you're running good chance of cutting into the conduit at 90° bends. Wide steel tape or rope is better. " frameborder="0" allowfullscreen>

Now that I offered what you asked for, let me ask you this:
Is there no way to have local amp and avoid pulling 2 16/4 speaker wires? How about fiber rather than cat5? What's RG6 used for? If Sat, could you install 2nd dish and not connect the systems? If it's cable TV or ISP services, couldn't fiber carry that signal?

~ how long is the conduit? Edit: Nevermind my question. I obviously missed the first sentence of your OP where you said " The contractor ran about 100 feet of 1" grey schedule 40 conduit"

The contractor ran about 100 feet of 1" grey schedule 40 conduit without inquiring what the needs were for this location. I need to pull two speaker cables 14/4 and a 16/4, one RG6, and three cat5 cables. I don't believe I have a chance. I am thinking 2 inch would be needed, with 90° sweeps at each end, and a couple 45s in the middle. Make sure to lay it out without tangles and twists- with lube, luck and a song in your heart, anything is possible.

All this talk about lube and pipe and not one single "thats what she said". Im proud of you guys.

Do you recommend I try to mount a cable box and two Sonos amps on the back of the television, which will be using an articulating mount?

No. I would try the suggestions about laying out some pipe and trying to feed some cable thru it. 100' is not that long, but if you have trouble then you might want to look at fiber and other options. If you could send audio over fiber, digital coax or toslink, that would save you some room in the conduit. Also, are your 90s closer to one end or are they evenly spread throught the run? If closer to one end, pull from that end first. It would be easier to back the pull out if you run into tangling issues. Again, lots of lube.

Take a piece of cloth, sock, whatever and use that to pre-lube the pipe. G E N I U S ! I don't know why you showed that cable puller, though. The "2" in the model number is the number of TONS of force this device can apply to completely shred the wires once you have 87 feet of cable in the tube and it gets stuck, despite the lube. The electrician who taught me how to pull wires made the point that with some pulls, you simply can't tape the wires together. You have to loop a piece of copper through the end of the fishtape so that the actual copper would have to be broken in order to lose a wire. If you just use tape, you're counting on the friction of, say, a foot of tape wrapped around a bundle, versus the friction of up to a hundred feet of conduit resisting the pull foot by foot. If you use nylon pull-string, be CAREFUL. Unless you use EMT, you're running good chance of cutting into the conduit at 90° bends. Wide steel tape or rope is better. Also genius.

Polypropylene pull rope is usually 1/4" or larger diameter (at least the stuff I use is). It works great for pulling big bundles or large conductors through large conduit, but it's going to be too big to use with all your wires in the 1" conduit. As mentioned standard pull string is not going to be a good choice either because it will be too stretchy, may not be strong enough and can cut into the pipe. My recommendation would be MuleTape which is flat. It comes in two different sizes and you'll want the larger for this job (part number 31-315). You've probably seen this stuff in larger diameter Carlon Resi-Gard flex conduit. Trust me that you'll love this stuff and it will become your favorite pull line: [Link: idealindustries.ca]Get a set of the foam carriers and quickly suck or blow the line through using your shop vac. I like the Greenlee version better than the Ideal Version: [Link: greenlee.com]Don't lose too much sleep over this. Use two guys, the MuleTape, a lot of electrical tape, a bottle of lube and then push & pull keeping the cables straight and not twisted. I think someone else mentioned it, but stagger the end of the cables. Start the second cable about 6" back from the first and continue. You'll end up using lots of electrical tape, but will have a nice pointy bundle that flexes easily at the end compared to a blunt non-flexible bundle if you just wrap up all the ends together. ShaferCustoms should also receive a big thank you for mocking this up and posting a photo for you. His advice to add an extra category cable is also good. I think you can squeeze it in and it might save your bacon down the road if there's a cable failure or change in design/future upgrade. P.S. > MuleTape!

Mule tape is the way to go. As is knowing how to make a proper head on the bundle by cutting the ends of the cables at angles, staggering and tying the head with 3 half hitches separated by about 4-6" each.
You could use a greenlee mouse to feed a jet line through to use to pull in the mule tape. Or, you could just make a mouse from a piece of a plastic bag. Just cut a piece about 6" square or so and make it look like a partially deflated balloon. Tie a slip knot on the back of it with the jet line and push it down the pipe a few inches. Use a shop vac on the other end to suck it through.
Now pull the mule tape through and fashion the cable head. For lube, the best stuff I ever used, albeit the nastiest, is Polywater. Once you use it, you'll be mentally scarred, but it works like nothing else.
Oh, and do NOT tape the wires together along the run. Make sure who ever is feeding, that they actually feed the cables into the pipe along with adding lube every few seconds. Do that and you'll be fine.

It may be obvious, but I'll say it anyways: When you're attaching your 4th, 5th and so on cable, do not tie them all together. Attache the cables to either your pull cable or the the first cable you're pulling. Otherwise, you're creating large knot that now has hard time navigating thru the bends.
Also, like someone has already mentioned, do NOT use tape, zip ties, string, etc. to bundle the cables along the run. Doing so have serves no purpose in the middle of the conduit (other than keeping cables from twisting); it could serve as sqeegee, puddling lube; and, adds to the bulkiness, making it harder to pull.

Thank you for all your advice and help. I was able to enlist the help of a friend and, with a quart of lube, it went surprisingly smooth. Thanks again, you guys are a great resource!
