Casement Window Operator Identification and Replacement

Hello, Jonathan. You have a very old style operator that's unfortunately not made anymore. Our modern 39-028E may replace it, but you'll note right away that the bearing at the end of the arm is different. Ours is round rather than square.

To make this work, you'll need to also buy the 39-533 track, which is compatible with the guide on our part. Just note that this is designed to mount to the face of the sash frame. I'm not sure where your track mounts, so this may still be a deal breaking detail. Your next step is to check where the track mounts on your sash to verify if our two products will work for you.
