Hey, Dave, thanks for posting. I've narrowed this Series down to two choices: either our Series 351 or Series 390 channel balances. However, I am not sure which one. The difference between them has to do with their bottom shoes. Check out our 15-001, which is used with the Series 390 balance, and our 15-002, which is used with the Series 351 instead to see which is a closer match.
Comparison of 15-001 & 15-002

When you say overall length, do you mean the length of the metal channel or the length of the entire balance, including plastic ends? We only measure the length of the metal channel, and do not count the plastic ends.

We do show a picture of the best way to measure channel balance length on the Series 390 page.
As you can see, the diagram only indicates the metal channel. Now, as for the top sash guide, I'm afraid that I cannot identify it while it is still in the window. Could I see a few pictures of it fully removed? I would also like detailed dimensions. |

The Series 390 uses our 19-002 top and 15-001 bottom. If you need the 15-002 bottom, then you're looking at the Series 351 instead. You should verify before you purchase anything.
As for the top sash guide, check out our 18-110. This appears to be a possible match. |
