I figured out the correct balance but the code on it says 27-4, is it the same thing at 2740? Double checking before I place the order, thank you!

Yep, 27-4 corresponds to our 2740 option. You can also weigh your sash to be sure, we have a chart on the S395-28 store page that tells you how much weight each option supports.
