I see the term is casement window operator. I need the entire mechanism, crank, arms, someone removed all of it.

Thanks for posting. I am confident we can help, but can you show me the operator in its entirety, including the arm that moves the window? A bird's eye view with the window open would be best. We should be able to narrow it down from there. Thanks.

Thanks for getting back to me. This looks like the 39-399 ROTO Straight Arm Operator. Just make sure the dimensions match what we show below. For a new Track Slider, see the 39-541. We don't carry that exact T handle, so you'd have to reuse your old one if possible--or, go with a different style, the folding 39-232. Let me know if you have further questions.
