S-377-15 option 1430 right?

Question

I am replacing channel balance for 5 old windows
I can see that S-377 is the closest one to choose. But the top part is slightly different from the original one. Could you confirm I made the right choice?

Thanks for posting! The balances you have look more like either the S380-15 with a 1" shoe or the S385-15 with a 1-3/32" shoe.

To determine which series is needed for your window, look over the dimensions from the diagram below to confirm the depth of your bottom shoe. Let me know if it does not match either measurement.

You'll need to select the 1430 stamp.
