Description

The design is directed to an aluminum extrusion performing an octagon shaped structural element of unequal sides to provide structural strength substantially equivalent to a square-shaped member while providing an aesthetically pleasing appearance. The corners of the extrusion are formed with a slight radius and the extrusion can be utilized as a structural element of aluminum fabrications so as to be visible upon completion of the fabrication. As an example, such can be used in the construction of a canopy shelter.

FIG. 1 is a top, left front perspective view of octopost extrusion showing my new design;

FIG. 2 is a front elevational view thereof;

FIG. 3 is a top plan view thereof;

FIG. 4 is a bottom plan view thereof; and,

FIG. 5 is a right side elevational view thereof, the left side view being a mirror image of the right side view shown.

The broken line showing in the figures is for illustrative purposes only and forms no part of the claimed design.

Claims
