Replacing 7073A Andersen casement operators

Question

What is the difference in 39-366 and 39-028E? They both have the same discription. My house has several Andersen windows and I would like to restore instead of replace. Most are in good shape, some are not. I need operators and handles. 7073A

Hey there. The 39-366 has a stainless steel roller and works with different tracks: the 39-504 and 39-520. The 39-028E works with the 39-507 or 39-533. Let us know if you have further questions.
