Series 350 sash window channel balances?

We can replace this balance for you, but it is not a Series 350. In fact, this balance has to be custom made due to its unique design. Can you show me the metal clip or hook at the end of that white cord? It should resemble our 62-108 or 62-106, among other possible shapes. From there I should be able to ID what you need.

Thanks for getting back to me. That's perfect, thanks. I just shot you an email with a custom link to order a pair of these balances stamped 19-5. Let me know if you have any questions prior to placing this order.
