Is my channel balance a Series 380?

Hello,
Could you please steer me in the right direction? I'm looking for replacement channel balances. Your 27" Series 380 Channel Balance look most similar to mine, but I need to know of they are appropriate for a 25 pound, non-tilt window. My sample is 27" x I've attached photos of my current balances, including a part number. I do not know the manufacturer though. Please advise.
Thank you!
Jason

You may actually have the Series 385 balance assembly, since your shoe appears to be a little deeper. Please take a look at our S385-27 Channel Balance.

You will want to choose a 2640 stamp option, which will carry a window sash weight range of 19 through 26 pounds.

Thanks for your help Donna. I just ordered 6 - hopefully they work out.
Take care,
