I'm looking to move this outlet to the other side of these studs, so that the outlet doesn't overlap with a wainscoting stile. Doing so will involve putting a ~3/8" hole though the studs to run the existing romex to the other side. I'd prefer not to use an old work box, as those seem kinda unstable for the long term, and instead opened the wall to install a new work box. Paneling is going over the hole anyway.
Question: Any idea why there would be two studs here? There's no window above it or door -- just a blank wall. Is it safe to drill through? I don't want to weaken the structure.
