While the shape sort of reminds me of our 55-076 Glazing Bead, I don't know if it's exact or if it would work. The problem with these long retainer strips is that the companies who made them constantly came in and out of business without preserving their designs, so finding exact matches can be really difficult. What I recommend you consider doing instead is discarding the long strips in favor of using an old fashioned method, which is more flexible and, in our opinion, more reliable. You would install our 70-180 storm door clip with the 33-020 screw. You would just need to carefully drill a hole for the screw. Take a look and see what you think.
