ABSTRACT:
A fence system comprises tubular plastic posts and at least one tubular plastic rail, the rail having multiple rail sections joined together end-to-end with plastic couplings, and the posts each having an anchor assembly slidably-fitting into a bottom of the post and extending axially from the post so that the anchor assembly may be driven into the ground by aligning the post to the ground and driving the anchor assembly through the post and into the ground. Each post is provided with at least one rail aperture having an opening on one side of the post that is slightly larger than the rail sections and having an opening on the other side of the post that is vertically oblong so as to permit a rail section to extend through the rail opening at a non-perpendicular angle without binding in the aperture. The anchor assembly comprises three elongated plastic tubes arranged to nest together parallel to one another, each tube having a beveled end arranged with respect to the nested-together assembly to provide a ground-piercing end for the anchor assembly.
