Replacement sash balancers

Question

Hi I'm looking to replace both sash balancers on old Andersen window. Not sure which number from your catalog is correct.

Thanks for posting. It's a bit tough to tell, but if one of the stamp engravings read '4#19', then see the 24-431. This can replace old Andersen Balances with the '4#19', or 419 stamp.
