Tip color for an S600-29, 30 lb. Sash?

A handy person from new jersey says:
This is a tilt window, 5/8" diameter, 29" long. This is a different window and it is larger - around 30 lbs. I think it is a S600-29. What should the tip color be?

Thanks for posting! I believe that you would want to choose the blue tip. An S600-29 spiral balance with a blue tip has a sash weight range capacity of 12 through 31 pounds.

Please keep in mind that the weight range capacity 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
