Marvin dual arm crank

Question

Probably 25 years old. Cranks open but won't close without manually pushing the window from the outside. Also the cover was lost by a painter several years ago. This is a bathroom window that is designed to open only about 6 inches. Thank you.

Thanks for posting. I'm sure we can help you replace this operator, but I need to be able to see the link arms in their entirety to know for sure which operator you need. Can you show us the operator and link arms from a bird's eye view, either with the operator out of the window or at least with the window open? That way we'll be able to narrow down what you need. Many thanks.
