Marvin casement window parts

Thank you for sharing your photos with us. Check out our 39-036. Does this look like a possible match? You might also want to check out our 39-035, its opposite handed partner.

I agree with you and Dave, our 39-036 looks like a close match to the operator in your photo. As long as our dimensions match then you should be good to go.

"Right" and "Left" is defined differently from manufacturer to manufacturer, and even in the same company from part to part. You'll tear your hair out trying to find one consistent definition of those two terms in this industry. Don't even bother; instead, focus on the design features of the hardware in question. Look at what side of the operator the gears are on, or the arms. That's how you determine the best match. For example, between the 38-036 and 38-035, the setup of your operator looks closest to the 38-036 since the gears are on the same side.

As for the 38-075 and 38-170, the biggest feature of the 38-170 is that it has a special 1/2" long post on the locking mechanism. The 38-075 doesn't even have a post, and since yours doesn't appear to, either, then I think you have your answer.

All dimensions for the 39-036 can be found on their store page. If you look under the main image, you'll see a couple of thumbnails. Clicking on a thumbnail will make that the primary image. I'll also post them here for your convenience. As you can see, there are really only two dimensions you need to be concerned about.
