Casement window operator and locking mechanism

Thanks for posting. For the sash locks, start by looking at our 38-095, 38-096, 38-138, and 38-139. Go over all the dimensions, particularly the projections of the fork, to see what matches best. Now, your operators look like our 39-091 and 39-092. Keep in mind ROTO has discontinued much of the hardware related to these operators, including the handle cranks and the bracket arms that connect the operator to the window. I apologize for any inconvenience. Let me know if you have any further questions.
