A quick learner from East Patchogue says:
I have a sash balance with nos. 11600-17 and W10 823-2-88 stamped on it . What is your corresponding replacement no. ? The window is approx. 36" high x 31" wide as part of a Bay window . Thank you ! Steve

I recommend that you consider our 24-847. This can replace balance boxes with the stamp 823.
