Channel balance 28cbsi

Hello there. We may be able to help, but that stamp does not tell us the channel balance's identity, but rather just its strength. To know what balance you need, please send us pictures of the attachments on either end of the metal channel. I'd also like a picture of the stamp, just to be safe. We'll do our best to narrow down your needs from there. 

Yes, that's a huge help, thanks! What you're showing me here is just the shoe, but it's a unique style that's only found on our Series 775. Based on your stamp, that'd be the S775-29 specifically. I think this may be what you need but you should check the other details to ensure that everything matches. We have detailed photos and information on the S775-29 store page that will allow you to verify.
