Need help identifying the right spiral balance

Question

I'm restoring my old windows and need help identifying the right spiral balance. I think it's called double hung window... both windows go up and down the the outer window has the smaller spiral balance which has no tube and is just the spring and spiral.I guessed the length and came up with 27 inches and a 1/2. I measured another spiral balance from another window which has a tube and it measures about 1/2 inch wide. The inner widow has the longer spiral balance which is about 29 inches and 1/2. I guessed with that one as well because it has no tube...the windows don't seem to weigh much without the glass. I'm thinking no more than 10lb to 15lb.

Hello,

We don't have an exact replacement for your balance, but our S500 spiral balance may do the trick. You'd need to use the S500-28 and S500-30 based on the picture of your balance lengths, but I'd recommend double checking and measuring the way we show on our product pages. You'll need our 17-012 to replace your old brackets. You'll also need to weigh the bottom sashes to choose the correct tip colors for your balances. Thank you!
