Hello,

I have a casement window in the kitchen and the handle is broken. The handle assembly part # OP05-7554-03.

Could you please let me know how to replace handles for both window panels?

Thanks
Manju

Looking at your photo, it appears you have an older version of our 39-330 Roto operator. We also carry the opposite side, the 39-329. You might be able to use these to replace your old version, assuming everything matches up. However you will need to replace the handle for the newer style spline. See the 39-205.
