In the last twenty five years, storm door companies have found that designing plastic retainer strips instead of using the old fashion storm door clips and screw is less expensive. The problem is that every door company changes the retainer strip almost every year and it is next to impossible to stock them. Unless you can go back to the door manufacturer, we suggest using our 70-180 storm door clip and drilling a hole for the 33-020 screw.
