What model would I need to replace the operator

A home owner says:
Hello,
Looking to replace the operator for my casement window because the mechanism opens the window but does not close the window when cranked the other way.

Casement window that is around the 1990s. Can you let me know what model this is?

Hello,

We'd be happy to help but we would need to see a photo of your operator with the window open so that the arms that operate the sash are fully visible. Thank you!

Great, take a look and compare the specifications of our 39-216 and 39-217 operators to your original assembly. Thanks for posting!
