window weight- spiral ballance color code

Question

where is your table for window weight and spiral ballance color code for the S500-28?  I do not know what a standard weight is but I know my window weight is 20 lbs.

S500-28 with the red tip option will carry a window sash weight range of 7 through 29 pounds.
This 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.
