As long as the studs are the "standard distance" apart, you should be able to hang it just fine. Unfortunately, I don't remember that standard distance and I can't measure it as I have moved to a place without enough room for the bag

So you'll have to research that one yourself.
That said, I think once you have the hanger set up, all you need is a way to anchor the bottom section of the double bag. I've never installed a double bag before, but I think you have the option of either using a weight, or anchoring it with masonry hardware. I think Title Boxing sells both options...
Let us know what you end up doing...
