Thanks for posting! Before we can suggest an applicable spiral balance, can you please give us the diameter of the tube? Can you also give me the weight of your window sash?
A handy person says:

Thank you. Based on that diameter, and the length, it sounds like you have something close to our S900-20 spiral balance. However, without a window sash weight, I cannot suggest a tip color for you. I will need to know the weight before I can. Can you remove the sash from your window and weigh it? Any common bathroom scale will do.
A quick learner says:
the window sash is 11lbs

Thanks for getting back to us. With that in mind, I would go with the red tip. This can support a window sash weight range of 8 through, and including, 21 pounds.

Please keep in mind that the weight range information is based on 2 balances per sash. Balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate.
