Non tilt balance

Thanks for posting! Your channel balances are either the S380-27 with a 1" shoe or the S385-27 with a 1-3/32" shoe. To determine which of these is the right replacement you'll need to confirm the measurement for the depth of your bottom shoe.

You'll need to select the 2650 stamp option.
