The stamp on our current channel balance is 3400 BSI NA. I believe that the S775 3400 is the right replacement, however I'd like some reassurance before I order it. I don't know the meaning of "BSI NA". Thank you!

"BSI NA" is just a manufacturing mark. You don't have to worry about that, what's important is the "3400." However, I cannot identify what you have without seeing pictures of the hardware itself.

Thank you. yes, the S775-34 looks like our best match. 3400 is the right stamp, so all you need to do is make sure you measure the width of your shoe so you know which 3400 option is correct.
