I think that it's 18" to the top. First, Section 1.2.2 describes the bar as being 18" high. Second, you have a 4x4 (3 1/2"

, a top plate (1/4"

, and a vertical bar (14 1/4"

that make up the 18". The fitting that is used there allows the vertical pipe to slide all the way through to become flush with the top of the fitting. I'll have to verify this tomorrow.
