I have some casement rear mount operators the style matches your 39-023 but it has a 9 1/2" arm not 11"

Dave Sr. from SWISCO responded:
We don't have an exact match for the 39-023 in that size, but what I would do is use our 39-138 operator and press in the 33-205 #10-24" grommet into the holes. This will let you mount it from the front. I would also recommend doing this is with the help of a vise. You might need to pick up new screws the correct size and type at a local hardware store if your current screws don't fit the #10-24 thread count.
