Need new casement cranks to replace Anderson 55003

Hello! That code, 55003, appears to be associated with a few different Andersen operators. The good news is that we only have two options to choose from: either our 39-150 with the 8-3/8" long arm, or the 39-094 with the 9-3/8" long arm. I'm very confident that you have one of these two, so all you have to do is measure your arm and pick accordingly.
