Hey, Thad. I actually don't recognize this part. Could you show me a picture of where it installs? That may help us find something similar.
There could be a sticker somewhere on your door that tells you what it is. Honestly, though, that's not often the best method of identifying individual replacement parts. For things like this, it's best to go on a part-by-part basis, relying on physical details and measurements instead of manufacturer designations.
