Odd shoe size

A quick learner from Florida says:
I have channel balances with the code 28B USB.
i see some similarity between my balances and a long Swisco discussion in Florida (Search 28B USB & 28C USB)
My main problem is the bottom shoe, which is only 7/8" from front to back. I don't see any Swisco options less than 1".

Your shoe is a little different, but I think our hardware can still work. We actually don't have anything smaller than 1", like you mentioned, but also keep in mind that these shoes tend to wear down a little over time. It's possible yours was once 1" deep when it was new. Even if it was made to be 7/8" deep, in the worst case scenario you could file down our 1" deep shoe a little until it will fit comfortably. With all that in mind, I would say the best match for this shoe is our 15-005.
