It’s actually 2 pieces, the part that connects to the sled, and the part that screws onto your MDR. So, if you’ve already got a bracket on your D-Box, you can just use the MDR portion - or the other way around. The D-Box portion should also work with the lovely double BFD mount from Tom Gelason, if you’re interested in that.
Since I own neither an MDR nor a D-Box 2 or 3, I’m not sure exactly what this is compatible with. If anyone would like any measurements, I’d be happy to take them, to confirm that things will work.
Make me an offer on this piece.
