I recently purchased two operators (39-022) from your firm but upon receipt found they are not what I need. They are similar in all aspects to my original operators except for the mounting screws; the replacements are mounted from the outside of the frame, while my originals mount from the room side. The accompanying pictures show both operators. The only markings I was able to find on the old unit was the number 6002-11L on the arm.
Please let me know if you'll be able to provide the units I need. Also, what do I need to do to return the unneeded operators.
Thanks,
Kurt
