Can you identify this alcoa window part

A quick learner from Annapolis, MD says:
I need to find the correct replacement for my alcoa windows. The piece is 33" long and is stamped with a 2230 on it.

Thanks for posting. Are you sure the balance is 33" long? With a stamp like 2230, I would think it was 23". Either way, it looks like our Series 350 channel balance. Take a look and see if you agree.

Sorry for the typo,

The balance (the metal channel)is 23" long and is stamped 2230. The length overall is 24" from point to point (including the plastic ends). Does this mean I am still looking for the 350 Series?

Thanks for all your help Tom, great site.

Ah, that makes more sense. Looks like you might want to consider our S350-23. Check it out and let me know what you think.
