Casement operator

Hey, Roman. I think I recognize this operator, but it's hard to tell from your photo. I only see the base, and it's still a little blurry. Would you be able to remove the operator from the window and show me a clear picture of the complete mechanism by itself? That would be a huge help, thank you!

Ha! Story of my life, Roman. I think I can throw a couple parts at you to consider in the meantime. 

Going by that screw in the base of the operator, I feel confident claiming that this is an older style casement operator similar to the kind Truth hardware makes. I've made a list of potential replacement options on this page that you can consider. I think these install on the sill the same way, but I can't speak for the style or size of the arm, especially the wheel bearing at the end of the arm. Those will be important factors when it comes to determining a replacement.

Thanks for getting back to us! Seeing the arm and the base plate is a huge help. I am confident that the operators I listed before are a good way to go, though without knowing the length of the arm or seeing the bearing at the end of it I can't really narrow it down further. It looks like the arm might be on the long side, so I'm leaning towards our 39-014, but you will have to measure the arm to confirm. I also strongly recommend confirming that the wheel bearing at the end of the arm is the same style.

There is also a chance you may need to alter the cutout in the sill trim for these to install properly. That may not be necessary, but the longer I look at the old operator the more I think that might be something that comes up. Just something to keep in mind.
