window balance box BL10# 314 8?

A handy person from Elwood, Il says:
My house was build in the 80's with Anderson double hung windows. I need to replace a number of the sash balances but the numbers do not match any of the replacements. The number on my existing sash balances are BL10# 314 8?.
Can someone tell me what the replacement sash balance will be for these windows.

Thanks,

Sure thing, Bob. Check out our 24-1033. This can replace Andersen balance boxes with the stamp 10#31.

I have one more sash balance I need to replace and the number printed on this one is C3 6#31. Could you please provide me with a number for a correct sash balance replacement? Thanks for your help.

Of course! I would go with our 24-637 this time. This can replace balance boxes with the stamp 6#31.
