I'm sorry to hear you're having trouble with this window. I see in the past you purchased a custom made 1320 14" long Channel Balance with a 19-008 top and 15-025 bottom. However, you did not purchase the other side. If you're using a new balance and old balance together, that could account for why it's still uneven. However, I also see you ordered an S385-26. This balance isn't meant to work on your window. If you installed that on your current window, it would likely not work properly. Can you confirm what balances you have currently in this window? |

Ah, okay! Thanks for clarifying. I think the reason the window isn't operating properly is that the balance springs are just seized up. This can sometimes happen when springs are old or corroded. Since the window operates properly without the balances, the solution would be to simply replace them, like you said. Based on the information you gave, you'd have a 26" long 2540 balance with a 19-008 top and no shoe for the hinge side, and for the opposite side you'd want a 26" long 2530 balance with both a 19-008 top and 15-025 bottom. I know you said 2520, but I feel like that's too light compared to the first stamp of 2540. You don't want the deviation between the two sides to be that big. If that sounds good to you, then we can custom make these. Let me know how many of each you need and we can email you a special order link. |
