Can I bring this Side Window Deflector aboard an aircraft in the US?

I recently ordered these window deflectors for my Mazda:

But I didn't account for the fact that they are very big, and don't fit in my suitcase (they are 45 x 3.6 x 3 inches in size). I am worried that I won't be let aboard the plane with them since they look kind-of "weapon-ish"...

Is my concern valid? Would it be legal to bring them on a flight from Ohio to New York?
