Hey there! Thanks for reaching out. Your operators remind me of our 39-391 (and its opposite part 39-392). Review the dimensions and compare them to your original casement operator to determine if this is the right fit for you. I am confident this is the replacement you'll need.

The compatible Folding crank kit for this operator is part 39-403. The opposite, 39-404 is compatible with the 39-392 operator.
