Hello! Your top sash guide looks very much like our 18-161, which is commonly used with the Series 380 channel balance. Look these parts over and see if you think they match what you have now. Take note that the Series 380 balance comes with a 19-005 top and 15-005 bottom nylon fitting. As long as those match, then you should be okay. |
