I need a help in choosing the size

Thanks for reaching out! I am confident that we can supply you with the replacement balances you need, however I'll need just a bit more information to confirm.

To start, I'll need to see a better photo of the top attachment from the balance, this is the end of the balance where the spring is on the balance. I'll also need to know the stamp/marking from the metal channel. This is what determines the weight range your balances should be able to carry to support the weight of your sash.

Please let me know if you have any questions.
