Window balance

A quick learner from Atlanta says:
I'm desperately trying to find this balance. I know now that it's called a constant force balance.

I was screwed over by a window manufacturer, called Premium Windows and doors from Pico Rivera, CA. They were setting up a new branch in Atlanta and I paid for windows from them. They installed and were going to come back the next day to add the balances. They didn't. The guy went back to Los ANgeles instead.

One of the windows had this type of balance, which fell out. I can't find anyone that has these or knows where to find or install.

Can you help?

Hello Michaela. I have placed a list on the upper right hand side of this page of different parts that may work for you. I encourage you to review this list carefully. If nothing looks familiar to you, I would then suggest sending us some additional photos of the parts from different angles. Also if there are any stamped numbers included, please provide them to us so that we may use that information to cross reference any additional parts.
