Hi Greg, thank you for posting,

To determine the correct stamp option for your window, you will need to remove the window sash and weigh it on a bathroom scale. From there, go to the S380-24 product page and review the stamp chart under the product description. Compare the weight of the sash to the chart to confirm the correct option.

Let me know if you have any additional questions!
