channel balances

Home Owner from St. Louis MO
I'm looking for a channel balance for my window. The number on the channel is 4030 and it also has the letters BSI. The length of the channel is 41" long.

Hello, thank you for posting,

To confirm the Series of channel balance you have, we will need to clear pictures of the top and bottom nylon attachments. From there we can confirm the best replacement option. Thank you!
