26" channel block. 25 4 GW CMC 11

A quick learner from Sacramento, CA says:
I had one of my channel blocks' line break and need to replace. Are these available through Swisco, or is there another provider of them? Also, should I replace the other channel block as well so both are the same? Thanks!

Hello!

It looks like you could have either our S380-26 or S385-26 channel balance. The only difference between these two parts is the size of the bottom shoe. With that said, you'll need to measure as shown in the image below to determine the best match. Based on your 25 4 stamp, you'd want the 2540 strength option.

And yes! We always recommend replacing your balances in pairs.
