Need these plastic strips

I have 15 year old AL frame "builder special" windows with these cheap plastic strips around the glass on the inside of the window. Many are yellowing and crumbling and need replacing. They appear to be cosmetic. Any chance you know where to get these?

This looks like the glazing bead for your windows. I don't think these are cosmetic, they keep the glass held in.

Unfortunately, I can't identify what you have from these photos. I would need you to remove a small sample so that we can see a clear shot of the end profile. Seeing the shape of the end profile is the only way to find a match. We will also need detailed dimensions. In the meantime, you can see our entire selection here. 

The videos below will also help; they will detail the kind of information we need as well as how to properly remove glazing bead.
