Need right side. Would like part numbers for both. Want to verify unit before I order more to be sure they are like originals. Thanks

I'm certain that we can supply the operator you need, but I'm afraid I can't identify it while it's still installed. Would it be possible to see it out of the window? At the very least, can you disconnect the long arm and show me a picture of its end? That's really all I need to see, as the design of the end of the arm is a vital detail.

You did not specify which end. This is the arm that is in window channel . As the other one appears as a permanent attachment. Let me know if further info is needed. Thank You.

Thank you! With this photo in mind, I recommend the 39-253LB. We also sell the 39-451 cover/handle set separately in case you can't use the original.
