# on larger window balance is 31 5 JX - CMC 7

# on the smaller window balance is 31 4 PG

The top and bottom are the same design in both

I need to replace the balances in 2 large AND 2 small windows

Hello!

We appreciate you reaching out to us. Depending on the depth of the balance's bottom fitting, you have either the S380-32 or S385-32. Measure as shown in the image below to see which Series matches up best.

You'll also want to select the 3150 strength option for the 31 5 stamped balance and the 3140 strength option for the 31 4 stamped balance.

Let me know if you have any questions!
