Need to see if you know what snap in glazing this is? It's 1/2 inch on each side and 5/8

Take a look at our 55-029, which seems to be a similar size to yours. You might also want to consider the 55-080. I have used this glazing bead by cutting the lock-in leg when it is too long to fit into the window sash. See what you think!
