Hello there. If you are referring to the window operator, see either our 39-253LB and 39-253RB, or the 39-438B and 39-439B. The difference between these two sets of operators is explained in the video below.

If you're talking about the casement window hinges, see if our 10" 36-004-10 Hinge Set matches what you need. Let me know if you have further questions.
