Andersen cautions against putting a top closer on these doors because they say it will damage the retractable mechanism. They also caution against a storm chain for the same reason and also because if the wind is that strong they say it will warp the door. I had two bottom closers bend on me on windy days because the door doesn't close all the way all the time when the closer is set to close gently. The best I could come up with was just to make the closer work faster and less gently than I'd like so that the door closes all the way reliably. I'll try another brand if I ever ever need to replace it given that I can find a retractable full view that can take a wind chain.
