Glazing bead
Thanks so much for reaching out to us. We unfortunately don't sell an exact match for this bead. Can you please verify its function and application? This looks more like a retainer for a storm door panel, but there is admittedly a lot of design overlap between storm door retainers and window glazing bead.
Thank you for clarifying. The problem with these long retainer strips is that each door company changes the style that they use almost every year. This makes it next to impossible to keep up. As such, we suggest considering using the 70-180 storm door clip and drilling a hole for a 33-020 screw. This is how storm door companies did it once upon a time, and we still find it to be an effective and simple solution.
The 70-180 would need to be secured on the face of the door with a 33-020 screw. The end leg of the clip has a 1/2" reach and should press up against the screen or glass panel in the door, holding it in place. I would suggest installing four or five on each side and maybe two at the top. Take a look and see whatb you think.
