Sorry, can't help finding that specific model. I assume you're trying to match shelves which are already installed. They should have manufacturer and model on them somewhere, perhaps on the side that's against the wall. Have you tried contacting whoever installed them? They might still have the purchasing paperwork.
There are lots of very simple "black floating shelves", though. Adding transparent bookends would then hold the disc cases vertical and let you see the cover pictures of the ones on the ends.
