Andersen window balancer

Question

Hi,
I've looked at a bunch of posts and nobody seams to have the same numbers as me. Mine are

11600-17
P60 12#26 11 83 One one side

11600-3
Us pat. 3,335,455
Pat can 1967 On the other side

Can you tell me the replacement for them? And are the left and right?
Thanks Mark

Hey Mark. See our 24-1231. This can replace Andersen balances with the stamp 12#26, or 1226. Let me know if you have further questions.
