S380-24 with matching top sash guide

I'm ordering S380-24. But, I need to replace a broken top sash guide, too. Which top sash guide is for S380-24? The weight of the sash is 13 lbs. Is 2330 the right option?

Hello, Thanks for all your help. I have used the S380 series for my sashes. However, for one of the sashes, I need to replace the top guide, too. This sash is S380-24, and the measured weight is 13 lbs (although its stamp says 23-3, suggesting 2330?). Anyway, please, check the attached photo, and guide me which top sash guide I can use for the S380 series. Thank you very much, SK

Thank you for your excellent on-line support. I have recently used the S380 series (S380-24, -27, -30) to replace several balances. I thought they were nearly identical, but it seems that there may be "subtle" difference. One problem I have is that the terminal clip doesn't engage the sash frame securely enough, so that the balances often fall off. When it happens, the plastic parts inside the balances tend to break. Could you kindly check the attached pictures and inform me if S380 is the correct replacement? Or, if there happens to be a better type of balance, could you let me know so that I will replace them?

Thank you again,

SK

I've done a quick measurement. It does indeed appear that 15-001 is the right shoe, not the 15-005. However, the Series 390 has a non-matching balance top 19-002. The Series 380 has 19-005 which matches my old balance. Can the Series 390 be shipped with 19-005 balance top?
