I rec'd my Mainstream a couple days ago. That's the good news, the bad news is it doesn't fit in my 4 outlet box with three DHC-2 power cords. Not a showstopper, just a hurdle.I know one other person here that had a similar issue, sorry can't recall who it was. Before Mark left he mentioned a possible workaround for this so I emailed him. Not my place to say it's not going to happen, but there is a large expense involved for tooling that I would take as "not feasible" to move forward.  Mark is going to look for a 90 degree adapter that could possibly work. I'm going to look into creating a piggy like extension cord and other ideas. For now I do have Mainstream plugged in using a 8" cheapo piggy. I've got a bunch of these I use to keep wall worts hogging up outlet space.

First, I'm going down the path of trying to use "quality" connectors/wires because it seems like the right thing to do to get the best out of Mainstream. Any differing opinions, am I over thinking this?

I know male power cord ends are easy to find, however, the female end seems to be elusive. Anyone aware of something better than Home Depot quality?

Since I'm not finding female ends (my wife should be grateful), perhaps I should consider replacing the DHC2 end with something more slim? At the wall outlet I have SDFB with Piggy in the top and Snubway on the bottom and they fit real close, but they fit.

And the final (so far) idea is to move from a 4 outlet box to a 6 outlet box.

Any thoughts or ideas are very welcome, thanks!

I have a couple of the older short Piggies and would be willing to move one along if you'd like one. Shoot me a PM if you're interested.

I got Mainstream to fit in a tiny little extension cord. It took some massaging to the ground post of Mainstream to get it to fit, slightly narrowing/rounding that post allows it to fit. For now, is seems like an ok solution. I also added graphene sluggos and have been breaking them in, so hard to tell if the tiny cord is a winner or not.

Sean from the image, the blue cork looks black and matches the top and bottom black rubber. I like that look the best! I think some black paint would do better than the marker, but you're on the right track.  Nice contrast of dark against light wood.
