Window balance stamp selection

A quick learner from Seattle says:
Unsure which stamp to choose for a 1/2" x 26" balance. Windows made in the 90's, plastic frame. No stamp printed on balance that I can see.

Thank you.

I'm not sure what you need, either. I see you were looking at our S385-26 channel balance. Is that what you have? If so, then I recommend that you weigh the window sash on a scale and see which of the options listed for the S385-26 covers that weight.
