Compatability of 70-172 w/ Pella

I don't believe the 70-172 can work with Pella screens. They usually use our 70-143P instead, but of course I highly recommend comparing your measurements and style with our pictures before you decide anything. It's also possible you do not have Pella screens, in which case the 70-172 is a real possibility. I would confirm that, just in case.
