Serial 19" and 5/8"s

Hello, thank you for posting,

Your window uses spiral balances. To further review, is your window a tilt in or non-tilt sash style? From there we can confirm the correct series for your window. Thank you! 

Great thank you,

With a 5/8" diameter and 19" tube length, please see the S600-19 spiral balance with a red tip option. The tube diameter will actually measure 9/16", but is considered 5/8" in the trade. 

Please review and let me know if you have any questions! Pricing can be viewed directly on the product page.
