Need new cranks
Thanks for your post! We do not have an exact replacement match for this operator but there are a few possible options that could potentially work for your repairs. Take a look over the 39-094 Andersen Straight Arm Operator and the 39-365 Single Arm Operator, carefully look over their dimensions and compare them to determine which of these might be the best option.
A previous customer provided us with a detailed explanation for installing the 39-094 and 39-095 and I believe the same could be applied to installing the 39-395 and 39-396. You'll need to examine the window. You can review the explanation here: Modifying 39-094 Andersen Operator.
The compatible hardware and accessories can be found in the related products for the operators, on the website.
