Looking to buy a few window dual arm operators to replace the old ones. I need help to get the correct kind.
Thank you,
Herbert

Hello, Herbert. Your operator looks like a match for either our 39-253LB or 39-438B, depending on the guide used at the end of the arm. The video below will go into more detail as to what I mean.
