Replacing glazing bead

A quick learner from Texas says:
Can you replace the glazing bead without removing window? I ordered some replacement bead but it was alittle small, not realizing how many there are. This is the original one that was taken off. It took me a year to figure out what these parts were even called. Can you help identify. Thanks

I would not recommend trying to replace your glazing without first removing the sash. It just makes the project a lot easier, and not to mention safer, due to the glass.

As for the glazing in your photo, this particular sample looks like our 55-029. Review our dimensions to verify that it's a match.
