Replacement single hung lift block

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

To start, I'll need to see both ends of the balance to determine the series. In the photos your provided, you show a photo of the bottom shoe attachment but not the top guide.

Please also confirm the length of the metal channel of your balances.

Let me know if you have any questions in the meantime.
