Mount-it MI-386 mounting plate holes distances
It's designed for 16"-apart vertical studs, but the studs over my fireplace are horizontal. They are about 11 3/4" apart (center to center) and I assume they are 2x4s sitting wide-side out as the stud finder shows about 3 5/8" height. So I assume the holes are 16" apart horizontally ("W" for width on my image), but does anyone know how far apart the holes are vertically ("H" for height) ? The overall plate is 18.1" by 11.7" so I'm guessing it's 9.6" if the mounting holes are the same distance h/w from the corners (hard to tell from the images) which MIGHT be enough for me, but if anyone has access to the plate to give me an exact measurement, I'd really appreciate it. Thank you.
