window operators there are 3 needed

A home owner from Michigan says:
There are 3 window operators needed. Two of them from the same pair of side by side windows, one is a left hand and the other a right. But they seem to be a pair.

The other is a single operator needed. Of the five photos it is the first or last depending on how they come through, but there is only one photo of that operator.

Hi there!

Take a look at the two sets of operators that we've related for you on this page. Look over our dimensions for each set and compare them to your original hardware to see how they match up. If you need a new handle as well, please see our 39-114L or 39-205, depending on the style you prefer.
