Sliding window sash balance 3230

Thanks for posting. Your top sash guide looks like a match for our 18-008. Look it over and let me know if you had any questions about this particular product.

As for the balances, you have either our S351-33 or S390-33. The only difference between them is the size of the bottom fitting, which is indicated on their respective store pages. You'll need to measure your bottom fitting to confirm which one is the better match.

Comparison of the S351 and S390 balance shoes.

Both balances I mentioned work with the 18-008 top sash guide. I'm afraid  you won't be able to determine which one you need until you get your hands on the original. Measuring that shoe is the only way you can confirm. There's no way around that, unfortunately.

Great, glad to hear you found a match. All pricing can be found on the S390-33 store page, which I linked you to above. This is also where you can place your order.
