Plain Round Non-Tapered Column Attic Base

Our dimension chart designed for our round non-tapered fiberglass columns is a comprehensive reference table that outlines the key physical specifications of each dimension of our column to help select the appropriate size based on design requirements, structural needs, and installation constraints.  Use this chart in all  applications such as porches, entryways, or porticos. Presented in a tabular format, the chart typically lists the nominal column diameter (usually the bottom measurement) alongside corresponding top shaft diameter to reflect the taper, available heights or lengths in feet, average wall thickness for durability assessment, and additional details such as bead width, cut-at-bead loss for trimming adjustments, and sometimes the first ring position or encaseable support sizes.

Our inside dimension chart for round non-tapered fiberglass columns is a practical guide that details the internal measurements of our hollow, non-tapered structural fiberglass columns, enabling our clients to determine the maximum size of load-bearing supports, such as wooden posts or steel pipes, that can be encased within the column for secure installation and enhanced aesthetic appeal in applications like porches or entryways. The chart correlates the nominal outer diameter of the column with corresponding inside diameters at the top and bottom of the shaft—accounting for the taper where the top is narrower—to specify the largest round or square encaseable dimensions, ensuring a proper fit without compromising the column's integrity or requiring excessive modifications during setup.
