Replacing Truth Hardware on rusted out windows

Thanks for posting. I'll try to go over each operator for you, in order. Note that I will require more information in most cases.

1. Starting with the awning window, my recommendation is the 39-239B. Review its specs and see if you agree.
2. For the single arm operator, I will need you to disconnect the arm from the track and show me a clear shot of the guide at the end of the arm. It's not possible to ID a match without seeing that.
3. I will need the same thing for the dual arm operator. Please disconnect the straight arm from the track and show me a clear photo of the guide at the end of the arm.

I'm very confident that we have the hardware you need, we just have to narrow it down.

Thanks! Assuming that your first photo is for the single arm operator, then that is not the 39-443. The black guide I see here is closer to the 39-529, which is a different style. My recommendation in that case would be the 39-449.

As for the dual arm, assuming that your second photo is what you need for that, then my pick would also be the 39-253LB, yes.
