3030 balances

Hello,

With this combination of attachments, you could have either the S380-31 or S385-31 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. You'll also need 3030 spring strength options for your replacement balances. 

Comparison of the S380 and S385 balance shoes.

As for your top sash guide that holds the balance in place below the sash, we should be able to help but we would need to see your guide uninstalled to compare to our inventory. Thank you!
