Attached is a picture of the balance shoe and the numbers on the spring balance. I do not know the window manufacturer. The balance channel length is 30". Do you have part? I need 2 channel balance.

I believe the balance is our S770-30 channel balance, though you will need to carefully match it up to your own to confirm. This is based on your shoe, not the stamp, so it is only an educated guess.
If this is correct, then I believe you will need a custom-made spring. 29-7 appears to be very strong and I don't think any of the standard options that come with the S770-30 will work. Please weigh the sash on a scale and we can tell you exactly what needs to be done. Thanks!

Great. I can make something up with a 30E stamp, which can support 29 through 33 pounds.
This is assuming you do have the S770-30. Can you confirm? Assuming we're right, I'm going to email you a custom order link and price quote that you can use to place an order on our website. Please let us know if you have any questions!
