This is a picture for a glazing bead for a 20+ year old Alenco window. I need to replace a fogged window and I am concerned that the glazing bead is old and brittle. So I need to have some spare bead available before I start.

Our 55-174 snap in is for Alenco windows, but that square piece at the end of your beading looks larger. Take a look at the 55-161 instead, maybe that would be a better fit for your window. If not, give us your dimensions and we can work from there.
