Searching for Stamp opinion 2420

Thanks for posting. The number you are referring to on your window balance refers to the spring strength. In order for us to determine a proper replacement for you, we would need to see some photos of the entire balance. If you could also provide some measurements and dimensions, that would be a great help.

Thank you for the picture. I would recommend either our S390-25 or S351-25 depending on the size of your bottom shoe.
