26-387 on Pella Vinyl

Hey, Ken. I've never used the 26-387 on a Pella window myself, but as long as the frame is flat and the tab can reach the sash, I don't see why it wouldn't. Then again, Pella windows are pretty particular, so I can't say for sure. I just don't know. I think you should first make sure to carefully examine the dimensions shown for the 26-387 to make sure that it will fit. You could also check out our video below for some more insight.
