  Poly-Classic Round Tapered Specifications

Poly-Classic column shafts are architecturally detailed and molded from fiberglass reinforced polymer (FRP). Caps and Bases are manufactured from low maintenance materials: FRP, fiberglass, polyurethane, polystyrene, etc. CAD prints are available singly in PDF (via email), DXF or DWG (via email), FAX, or on drafting vellum (24" x36") upon request. Split columns and split/reassembled columns are NOT load bearing. Columns must be painted. Please see installation instructions.

* Actual outside diameters are approximately 5/16" to 1/2" less than shown.
** Actual inside diameters may vary by 3/8".

Poly-Classic column fluting is held up from the bottom of the shaft for a few inches to allow field trimming of the shaft for less than nominal opening heights. The following table shows that distance, assisting in choosing between Tuscan or Attic bases, or differing heights of ornamental caps.

Tapered column shafts generally have a straight portion at the bottom before the taper begins. At the point of the taper, the space between the shaft and the base begins to increase as the column is cut shorter. While that space can be easily filled and caulked, the information in this table will help determine how much of the shaft is straight and where the taper starts.

The measurements for Inside Round and Inside Square are helpful in determining the largest size of support device that can be used inside the column. The primary basis for these figures is the approximate inside top diameter (narrowest part of the shaft.)
