I have found similar ones that look the same but they do not look like the have the same angle in the downward motion. The only model number I found was on the screen frame itself B-X1185AR.

I am afraid I can't cross-reference that code to a specific roller. Its design reminds me a bit of our 84-068 or maybe the 84-008M, but look over the dimensions for both rollers and see if either of these match what you need.
