Sounds like a problem with spring strength. It's possible the balances you ordered are too weak.
I note you chose the 1210 option. Are you sure that's what you needed? Two S385-13 balances with a 1210 option can carry a sash weight of 3 through 6 pounds. How heavy is your sash? |

I see. In that case, I see you ordered 18 of these balances. I would try another pair in another window and see if you have the same problem. I'm trying to see if this is just an isolated problem with those balances and that window. If you can confirm one way or the other, we will work from there!
