Thank you for posting. Unfortunately, this type of operator is discontinued and is no longer available. However, we may be able to come up with a substitute. Could I see what the clip at the end of the arm looks like?
I'm sorry, I meant the end of the link arm itself. I can't really see it under the sash while it's still installed. Can you unhook it and show me the end?
Can you also tell me the total length of the link arm?
