I think this will fit most storm doors. There is a slot on the underside of most storm doors that it simply slides into. I have an AMCO/Anderson model and it glides great. It's weird that you can't find them at most hardware stores. I also tried checking out Anderson's website and they wanted significantly more for it. I bought my house without this installed and noticed a draft coming from the door. This got rid of that draft :) And all those ants that came from the opening last spring. Very happy with this purchase.
