Thanks for reaching out! Your Andersen balances appears to be our 24-837 based on the 827 stamp shown on your balances. This balance is not specified for left or right, so it can be used on both sides of the window. You'll need to be absolutely sure that the balances you are looking to replace are stamped with an 823, 827, 831, or 837. Otherwise, this will not be the correct balance for your window. |
