Looks like I'll be doing this too!
Time for me to become Handy Man Pedro!
I watched it, just to see what you're talking about... nice that it makes installing new boxes neatly a lot easier to do...
When that video ended, the one that came up next was similar... but their boxes were also connected by a flexible plastic tube... for future-proofing... later on, if you wanna add some other kind of connection, you just fish the wire down the tube and it comes out the bottom... easy peasy... you might never need it, but if you ever do, I bet you'd be glad you got it... no idea what any of this costs though... https://www.youtube....h?v=xSqbXl5m4_o
