Operator search

A quick learner from Pennsylvania says:
Here is the picture of my broken operator. It seems to have dimensions close to the 39-031 model:
10 11/16" x 4 7/16"

Notable, my outer arm has a step up, but your 39-031 seems to have a step down. Will that make a difference?

I agree, the 39-031 looks like a good match. When we started selling this operator, we asked a casement window company why they had an offset arm going down. Their feeling was that with the downwards facing offset, it would stay attached to the sash stud even if the clip became detached due to the extra pressure on the sash stud. Hopefully that makes sense!
