I'm afraid I don't know what balances you have based on this information. I recommend that you look at our Channel Balance Home Page and follow the steps in order to find the Series that best matches what you have.

Thank you for the additional information. Did the bottom shoe once have wings attached? It looks like they may have broken off. If so, you should consider our Series 350 channel balance. Check it out and let me know what you think. If you also need the top sash guides, see our 18-172.
