Good afternoon, I'm looking to see if anyone could help me find what type of glaze bead I have here in the uploaded photos. Any help would be greatly appreciated! Thanks!

Thanks for posting. This glazing bead has a very unique shape, but it reminds me a little of our 55-158-6 Rollyson Snap-in. Compare the end profile dimensions below to your old seal and let me know if this seems to match what you have, or if anything differs.

Thanks goes to you Bob! I was thinking the same thing and after further inspection I believe the profile matches the 55-158-6 Rollyson Snap-In. Windows were installed in 1989 and never been re-glazed and/or sealed. I'll be placing an order for one 6' strip just to be certain, then place larger order soon after for the whole house.

Appreciate your time and expertise!
