ribbed channel balance

A quick learner from Chicago says:
I need 1 ribbed channel balance but mine has a blue locking terminal. I don't see any pictured. Are they available?

I see you were looking at our S751-33. Is this the balance you have? If so, the color of the shoe on the old balances is what they used to indicate spring strength. Two balances with those blue shoes were the equivalent of our 32TG option, which can carry 29 through 36 pounds. I highly recommend weighing your own sash on a scale to confirm.
