Vinyl Glazing Bead

I have some window bead that needs to be replaced, it's 20+ years old. I took a sample to some local window shops, to no avail.

I have included a picture. It measures .375 X .535. Is it still available? If not, what would be a good substitute?

Thanks,
Steve

I have the same problem with very old and cracking beads. The bead that I have to replace looks exactly the same as the 55-062 but my window size is 45x25 and the 3" is not long enough to cover the whole lenght of the window. The shipping cost for the 6" is little too much for me so my question is: can I use two shorter beads to make the 45 inch bottom/top of the window or it has to be one 45 inch piece? Thanks for your honest opinion. Daniel

Thanks Paul. I think I made up my mind and get the 4 3" beads to cover my project. Thanks again.
