Thanks for reaching out! Your casement operator reminds me of our 39-175 Pella Sash Crank Operator. The opposite handed version is part 39-176 and the compatible crank handle is part 39-109B. Take a look over the dimensions below and compare them to your existing operator to determine if this is right replacement. Dimensions for 39-175
