Your operator looks very close to our 39-239B operator. Take a look and see if you agree. Is this operator the original operator that was installed in the window? How old are these operators? Get back to us and let us know. I will forward this over to our senior expert, once you get back to us, to see if he has any additional input he'd like to provide. |
