Thanks for posting. We may be able to replace this balance, but I'm not sure about that stamp. Please give us a little more time as we look into the possibility of supplying that specific code. In the meantime, can you tell me how many you need? |

Thanks again for your patience. In addition to knowing your quantity, I would also like to know the exact weight of your sash. That will help us determine what you need. |

I'm afraid we will need that before we can proceed. These springs are specifically calibrated to a certain sash weight range. This is usually indicated by the stamp, but yours is very strange and we weren't able to cross-reference it to any weight range. We will need you to remove the sash from the window and place it on a scale so we can calculate the proper spring strength. It's important to be as precise as possible, down to the ounce, so that we know for sure what you need. |
