DuraGlass Round Tapered Shafts
Standard DuraGlass column shafts are the same height as the listed size. Tuscan cap and base and Attic base go around the shaft, and do not affect the overall height. Ornamental capitals are set on top of the column astragal, and will affect the overall height: see the Poly-Classic ® Ornamental Capitals specifications( page 18) for available capital sizes and more information.
