There are more breaks in the 24" version vs other size due to size of the banner stand case.
Because of the size of the 24" Shark and Super Stand Case, the 24" pole actually has 2 breaks in it versus have only 1 for the other sizes.
That said, you can actually use the 24" version with all of the different size options but you can't use the 36", 48" & 60" pole with the 24" as it won't fit in the case.
