Need to replace the spring balances in one window. Metal channel of the balance is 24". Stamping says 2330K (the K is stamped backwards)

They look like series 351 to me. Can you help identify for sure? Thanks

Hello, thank you for posting,

It appears you have either the Series 351, with a 15-002 bottom attachment, or Series 390, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need.

You will need a 24" balance with a 2330 stamp option. Please review and let me know if you have any additional questions!
