Casement windows operators

Hello,

Unfortunately, we were unable to locate an exact replacement for your operator. We do carry the 39-022 operator that is similar to yours, but it does not use the 39-529 track slider at the end. It has a metal bearing at the end of the arm. 

We do carry the newer style 39-450 Encore operator, which takes the 39-529, but I'm not sure if you can adapt it to work for your window. Would it be possible to use the 39-022 operator and replace your track with the 39-504? Take a look at the related parts and see what you think.
