What are the options for?

A quick learner from North Carolina says:
I finally find the part I need (15" Series 765 Balance
Product Code: S765-15 ) for my single hung window but do not know what the options ( 1,3,5,7,9 ) are for.
I have a 31" long broken sash cord; but because the windows are 7+ years old, I would gladly by several assemblies.

Thanks for posting! I see that your channel is stamped with the number "14 3." I recommend the 14-3 option, then. This can carry a window sash weight range of 8 through 12 pounds. Does your sash's weight fall within that range? Weigh your sash and let me know!

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.
A quick learner says:
approx weight = 7 pounds.

In that case, you would want the option of 14-1. This can carry a window sash weight range of 5 through 8 pounds.
