Casement window mechanism

A quick learner from East Nortiton, PA says:
The mechanisms for both windows are stripped and no longer function. I'm looking to replace both but I'm not sure how to measure or if the numbers in the photos are helpful. Any guidance would be much appreciated! Thank you.

Hello there!

Our 39-035 and 39-036 Truth operators were the first to come to mind. Look over the dimensions and compare them with your old assembly to see how they match up.

If you have any questions just let us know!
