Looking for window operators for jalousie windows. Can't figure out what brand.

I'm afraid that I couldn't find an exact match for this operator. It was tough to match up anything with the same combination of hole pattern style and link arm style. The est options we appear to have in our inventory are the 39-193 and 39-194, which are the same part for opposite side windows. 

I recommend carefully measuring your own part and comparing them to our dimensions. Please be as precise as possible, especially for the hole in the link arm. If your operator dimensions differ in any way, let me know exactly how and we can try our best to find something better.

Dimensions for 39-193
