Harvey casement window

Hey there. This looks a bit like the 39-090 Operator to me. Please compare. One issue is the link arm on the replacement is 5" long. From the pictures it seems yours may be shorter. You could try re-positioning the bracket arm attached to the sash to compensate for this difference. Or you could swap out the link arms with a rivet like our 62-014B. Let me know if you have questions.
