Window Sash Balance
Thanks for reaching out to us! I am confident we can provide you with the balances you need but I'll need just a few more details to confirm the correct replacement. To start, it looks like you've only included a photo of the top attachment, may I please see a photo of the bottom attachment? I'll also need to see a clearer photo of the pulley in the center of the balance, where the string and spring meet.
Please don't hesitate to reach out with any questions.
Thanks for those photos! They help a great deal. The only photo missing is the photo of the pulley at the center of the balance. Once I have that, I'll be able to confirm the exact replacement you need.
Feel free to reach out with any questions.
Thanks for the additional photos. You balances can be replaced with our either our S380-21 with a 1" shoe or our S385-21 with a 1-3/32" shoe. To determine which of these is the correct replacement, you'll need to confirm the measurement for the depth of your shoe.
You'll need the 2030 stamp option.
