Window balances

Thanks for writing in! Based on the information you've confirmed, it looks like you'll need the S385-17 and the S385-30. Although, to confirm that these are the correct replacements, with certainty, I'll need to see a photo of your balances removed from the window.

For the S385-17, you'll likely need the 1640 stamp option. For the S385-30, you'll need to obtain the exact weight of the sash these balances support. Once you have the sash weight, you'll be able to select the stamp you need using the chart below the product description.

Please let me know if you have any questions.
