Window glazing bead
Hey there!
It's tough to say from these photos. Would it be possible for us to see clearer photos of the end profile? You're also welcome to browse our section here in the meantime.
Thanks for your patience while we looked into this. I don't think your glazing bead is from an Andersen window. It looks similar to an older style we used to carry, but has been discontinued and obsolete for a number of years now.
What I used to replace that old obsolete part was to use the 55-029 or 55-197, which is a little wider. However I'm not sure what would actually fit your window frame. Take a look at those two glazings for now and see what you think.
