Thanks for writing in! Take a look at our 39-332 Andersen E-Z Straight Arm Operator. The opposite handed version is part 39-332. Look over the dimensions and compare them to your existing operator to determine if these are the replacement operators you'll need. You may also need to use the 39-362 Andersen adapter plate.
These operators are compatible with the 39-152 classic operator cover and 39-267 classic handle.
Hello,
This looks like the same type of Andersen operator shown in your original post above. If so, take a look at the 39-332 operator that Jasmine recommended in her response, as well as the other related parts. Thank you!
