casement window operator

Thanks for posting. I am afraid I could not cross-reference those codes to anything in our history. In general, the most reliable way to ID window operators is to send us pictures. A bird's eye view, either with the assembly removed from the window or at least with the window open, would be best. That way we can see the body, the handle, the arm(s) that push and pull the window--the whole thing. We should be able to help from there.
