Crank replacement

Thanks for reaching out! It is not likely that these would work to replace the Pella folding crank handles unfortunately. These are made to fit mostly Truth brand hardware, which typically has a spline measurement of 11/32".

To determine if there is a replacement handle and cover that we can recommend to you or to confirm with certainty that the 39-376 would not work, I'll need to see a photo of your existing casement operator.

Please feel free to reach out with any questions.
