Need to replace channel balances

Question

These windows are around 30 years old.  The only markings I find on the channel balance is 1610 b.  What would be compatible for these windows?

Hello, thank you for posting,

The 1610 marking informs the spring strength needed, but not the series of the balance itself. To further review, we will need to see pictures of the channel balance removed where we can see clear views of the top and bottom attachments. From there we can determine the series your window uses for a possible replacement option. Thank you!
