Identify part to be able to order please

Hello,

With this combination of attachments, you could have either an S380-24 or S385-24 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 2330 spring strength options for your replacement balances.

As for your top sash guide, see the 18-161. Thank you and let us know if you have any other questions or concerns.
