We had one snap off. Casters appear to be designated by caster sizes and rod sizes. Taking it all apart to pull one off right now would be a real pain. We can kind of move it by holding up the corner with the broken one (which is going to be a total pain to remove when that time comes). Can you tell that I am annoyed? I probably should not be because everything has a lifespan, but I just don't need an annoyance right now, I guess.
