Thanks for posting. There should be a few numbers, or even a few numbers and letters, stamped on the surface of your balance's metal channel. If you let me know what they read, I can tell you the best option to choose!

Thank you. Based on those stamps, I would go with the 2550 stamp option for both balances. However, that option is meant to carry a sash weight range of 25 through, and including, 28 pounds. Can you reweigh your sash? Did you remove it fully from the window? What is the exact weight?
Please keep in mind that the weight range information is based on 2 balances per sash. Balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate. |

I see. In that case, you have two options ahead of you:
Our 2520 stamp option can support a sash weight range of 9 through, and including, 15 pounds, while our 2530 stamp option can support 15 through, and including, 19 pounds. See which one would work better for you. I would also recommend that you double check the stamps on your balances, and triple check your sash weight. I don't know why the balances for this window would be stamped 25 5 for such a light sash! Did you ever have trouble lifting it up? |

It was my pleasure! I'm glad you're safe from the wildfire. Let me know if you have any more questions, and I would be happy to help!
