Code on cords in walls?

[Innovate1]

Putting a tv on the wall and don't want the cords hanging down. For receptacle I can put a box above and existing box that is low and fish romex so I think I'm good there. Then using some box covers that have a bell shaped opening pointing down for low voltage (HDMI, USB, etc. Recalling there are some cable ratings for running in a wall. How is this done to meet code?

you need CL rated wires- either CL2 or CL3. 2 is rated for upto 150v and 3 is rated for upto 300v... take your pick.... just keep in mind cordage is not rated for in-wall use... the ratings were taking here are low voltage signal cabling

I have "dropped" (fished) some pre made HDMI, USB cords down the inside of my wall and really don’t see an issue with it as long as it is 4-6’.…… To code? NO.
Mr. Wylie is correct but I see no harm in what I suggest.

BTW! They make a surface mounted plastic cord cover that can be painted to match the wall color.

I use these, one high and one low mounted on the same stud. For my own house I just dropped the regular ol' HDMI cable down. When it's someone else's house, I put a pull string between the two boxes and tell the owner that they are supposed to get cable rated for in wall use but also let them know that I can't see a problem with cable available at any Wal-Mart or box store.

I plan to make the run to the 120V receptacle to code (except fastening the cable in the wall which I am guessing no one does when fishing NMb to add things) but going to use regular cords for the HDMI and low voltage stuff.

The NEC does not require fastening the NM-b to the studs in an existing wall when fishing a wire. But you should use boxes that have a cable clamp.

I think that was the point - there are many items available to make the cable entry/exit a bit more attractive and not just a hole hacked in the drywall. I did some of this years ago and there weren't as many readily available options.

Oops. Now copy and paste won't work. It's the OnQ low voltage brush.

Lots of good suggestions. I used one of these for our living room TV and just bought two more which I plan to use in the garage for the TV and computer monitor.

I wired for power and low voltage 20 years ago when we built the house. But flat screens weren't a thing quite yet so no boxes behind the high wall mount for the current TV. So I just extended the power up to an old work box and used these to run the low voltage from the short equipment rack up to behind the TV came with ring, brush, and cover plate. Wife didn't like the cords showing and I agree it looks better without seeing them. Don't think I had seen the brushes before people posted them here so thanks for that.
