Hi!
We just bought a house and have some windows that don't work. Previous homeowners left box that came from you: great news! I however wonder if they are the correct parts? 29' long is good, tabs broken off old part? Don't look like it. Old number 2820F, new number 28 3 BSI. Old spring about two inches longer and set about inch lower. Window opens easily, but hard to pull/push down. Do you think they are correct, or can you supply correct number?

Hello,
You have a good eye and I agree that these we're probably ordered incorrectly. Based on the photo of your original balance, it looks more like either our S351-29, with a 15-002 bottom attachment, or S390-29, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need a 2820 spring strength option for your replacement balances. Thank you!
