Plastic Glass Holder

I'm afraid I don't recognize this part. You describe it as a glass holder; could you go into more detail? Is this a retaining strip for a screen or glass storm door panel? Or is this a snap in glazing bead that holes the glass in a window sash?

Would it also be possible to have dimensions of the end profile?

Aha, I thought so. Now, retaining strips like this are hard for us to supply, since every manufacturer makes something different for every kind of storm or screen window they sell. There's about a billion different kinds that are being updated and discontinued all the time. It's hard to keep up!

Fortunately, we have a nice and easy work around. We recommend using a clip like our 70-180 and installing it using a screw like our 33-020. This is what screen manufacturers did back in the day and we find it's a method that still works well now. Let me know what you think!

If you don't like that, then you could also theoretically cut your existing retainer into equal pieces and use those pieces. You don't need the entire length, so you could play around with it and see if that would work.
