We are attempting to verify that the parts below are correct.
We believe we need to order 39-099; 39-267 and 39-152 (?) for our window.
I'm sorry to hear that you're having trouble installing your new operator. I don't see any major differences in your photos that would have prevented the 39-099 from working for you but I'm going to have one of our senior experts take a look and see if they have any ideas. We'll reach out as soon as more information is available.
In the meantime, could you go into more detail regarding your concerns and the differences that you noticed that you think would prevent the new operator from working for your application? That could help us point you in the right direction.
