 Hello,

It looks like you have either our S351 , with a 15-002 bottom attachment, or S390 , 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 2650 spring strength option for your 27" replacement balances. As for your 33" balances, you would need 3260 strength options based on your stamp. The strength option is based on weight rather than size, so it's possible that your windows may be similar weights despite being different sizes if they are made of different materials or have different glass thicknesses. The 3260 strength option will support a sash between 32 and 35 lbs. I would recommend weighing both sashes to confirm if they fall within that weight range. 

There is a chart under the balance product description that shows the weight ranges supported by each strength option. Thank you!

I measured and I have bottom 15-001 , how do I know the top S351 or S390 . Also, the weight on
Smaller window is 20 pounds and wider window is about 30 pounds. They both have 32-6 balances. Should I use lighter balance for 20 pounds windows?
Thanks

Both balances use the same top fitting, so you would need the S351 channel balance. For your smaller 20-pound sash, you would need a 3230 strength option that supports between 18 and 23 lbs.
