Actually the drawing calls out "1 1/4" Schedule 40 aluminum pipe". The 1 1/4" refers to the approximate INTERNAL diameter, Schedule 40 refers to a particular standard the pipe conforms to. The standard deals mostly with the pressure rating of the pipe. But since the pipe is sold with the spec marked on it, it is often specified this way even when pressure is not involved.
The outer diameter in this case should be 1.900 inches. So Woodie's "just over 14 inches" is correct. Since the top of the lower bar is supposed to be 16" off of the carpet.
PVC pipe is also sold in Schedule 40 but because the mechanical characteristics of the material are different, so are the dimensions. But all diameters of Schedule 40 pipe should handle the same pressure regardless of the material they are made of.
You must not only read, but also understand what you read.
