Series S Coil Balance replacement help

A quick learner says:
I just received my coil Balances and I guess I ordered the wrong lbs ones. I got the 3 lbs but they do not keep the sash up... I was going by a number written on the old one (3) thinking that was the lbs I needed. The only thing I see stamped on the old one is 7.09X. My sash measures 22 1/2W x 26 H, double pane glass. Please let me know which ones I need to order.

Good Afternoon,

Sorry to hear you ordered the wrong coil balances. Which coil balance series did you order?

I want to make sure you get the correct strength this time. Please remove the window sash from the window and weigh it. Respond back to this discussion with the weight so that I can determine which strength you will need.

Here is SWISCO's return policy if you would like to return the incorrect coil balances.
A quick learner says:
I have the Series 180. The sash weighs 13 lbs on a baby scale :)
I am not worried about sending the others back. They were my mistake and I will just keep them and use them as temp backups for any other that might break.

Thanks for getting back to us.

I've double-checked my references, and it appears you need the Swisco S180-4 Coil Balance.

Let us know if you have any additional questions. We'd be glad to help.

You're quite welcome. Good luck!
A quick learner says:
Hi Mike, Those S180-4 you said I needed are not strong enough either. The window will nor stay open if it is opened around 8 inches or less.

I apologize our recommended coil balance didn't work with your application. I am currently looking into the issue and will post an update with more information as soon as possible.

Thank you for your patience.
