Thanks for posting. Sounds like you have a 32" block & tackle balance with a stamp option of 3130. I'm afraid that's all I can tell based on your information, though. Now you just need to pick out the top and bottom fittings in order to determine the Series.
I recommend that you look at our Channel Balance Home Page and follow the steps in order to find the Series that best matches what you have. |

I I'm a little confused. You say you have no stamp on the balance at all, but in your first post you said that it has "31 3" stamped on it, which usually corresponds to our 3130 option. Fortunately, this will work with a sash that weighs 20 pounds, so you should be okay.
