I just measured the openings in between the studs, and it's 15", 15.5", 15" wide and 7" front to back. That wire leads from the other outlet, on the dining room side, to the outlet in middle of where I want the stand, on the wood floor side. I'm planning on moving this outlet that's in middle of the wall I'll be taking out, to the inside of the stand where all the electrical will be. I'll have it switched over to a gfi relay (I think that's what the electrician called it) since a dedicated circuit is nearly impossible in this location (and I don't feel it necessary).
