Searching for 57020

A quick learner says:
I am looking for the Roto casement operator in the pictures. It is 3-1/4" from the center pin to arm pin. The distance between the window mount screw holes is 4". I found one listing the said the model # is 57020 but is obsolete. I am looking for 1RH & 1LH operator at minimum. Any lead on a source or alternative operator that is compatible would be appreciated.

The operator you show in your photo is no longer available. There is one solution I've heard of. I have never tried it personally, but I was told that you could use our 39-091 and 39-092 operators and 39-522 bracket. You will also need to replace the handle with our 39-224, and you will likely need a spacer like our 39-557. See what you think. You might want to get a contractor or handyman familiar with repairing windows to help.
