Pella Window Crank needs changed to folding

I'm hesitant to recommend the 39-403 and 39-403. I think they could work, but Pella products are so weirdly specific. I've been burned before trying to stray from the hardware that was originally installed. As a result I tend to just stick with what was installed originally, just to play it safe.

I understand that that doesn't solve your blinds problems, but to be honest there's no guarantee that going with the 39-403 and 39-404 will, either. In m experience, folding operator handles also get in the way of most blind treatments. In almost every single case I've come across, the solution ends up being installing the blinds further out so that they don't get in the way of the operators. In other words, the blinds have to make way for the window, not the other way around.
