Hello, thank you for posting,
Please review the style of the 38-097 and 38-098 casement locks. Compare the dimensions to confirm a good fit! We also recommend replacing the keeper with the 38-079, as your original may not be compatible with the newer lock style.
Let us know if you have any additional questions!
