Casement window operator

A home owner from Hawaii says:
I have several casement operators that need to be replaced. Can you advise as to the appropriate replacement models / process for retrofit? The mechanism appears to be located inside the wood frame.

For completeness, I am attaching a photo of the locking mechanism as well.

Thanks!

Hello, Thanks for posting with photos!
The operator looks similar to the 39-031 or 39-032 . You will need to carefully compare the measurements of the arms, just let us know if they differ in any way. Check out this handy how-to video for the removal and installation of your new operator:

For a new operator cover you can replace it with the 39-107FK

For the lock, take a look at the 38-075 , you will also need to replace the 38-089 , keeper to assure it will work with this lock, the size has changed.
