If your company is making a better spiral balance, then that is great, but I would have to see some type of specs that show some major improvement in design and see them proven over at least a 20 year time span to change my mind on spiral balances enough to ever use them again..
I spent a sizable portion of my career running service calls from 1975 to the mid 90's tightening and/or replacing spiral balances instead of doing what I should have been doing......replacing windows.
They have been the number one reason for service calls in the window business in the past, so my distaste for them is well founded and based on the time and money I have lost in my life because of them.
If your company is making a better one, then I'll have an open enough mind to consider changing my blanket statement about them, but I'd like to hear what is different about them before doing so.
