Awning window mechanism

Hello, thank you for posting! Can you please show us the entire assembly, including a full view of the arms? We particularly need to see the attachments at the ends of the arms. 

Thanks for getting back to us with those pictures. Take a look at our 39-143 and 39-324. Review their dimensions to see if either could work as a substitute for you.

We believe the 39-143 is the closest match for your operator and is the most likely to function as a substitute. However, sill modification is sometimes necessary. You can review our return policy here. Good luck with your repair!
