Pella Proline Casement handle hardware replacement

Hello,

We do offer the 39-403 and 39-404 Pella folding crank and lock kits. To confirm if these parts would work with your original operators, we would need to see a top-down photo of the operator's arms with the window open as far as it can go and the screen removed from the window frame. The more we can see, the better. Thank you!
