Operators ,

Thanks for reaching out! Your casement operator appears to have an operator base from Truth and the clip at the end of the arm appears to be Roto. So it is likely that your operator was adapted to fit the Roto clip.

With that said, take a look at our 39-449 and its opposite handed version part 39-450. This is used along with the 39-529 slider and 39-528 track. Also, take a look at the 39-457 (and its opposite 39-458) with the 39-520 track. Review the specifications for each to see if you could adapt the track to your operating window.

The 39-375 & 39-376 (folding) and 39-451 & 39-452 (non-folding) handle and cover kits are the parts compatible with the operators mentioned above.

Feel free to reach out with any questions you may have.
