Abstract
Traffic channeling device includes a delineator stem having hollow upper and lower portions, the upper portion being stepped inwardly along its axial length to form sequential stepped surfaces from the bottom to the top of the upper portion, and the lower portion being frustoconically shaped. Adjacent the bottom of the delineator stem is a radial flange portion which resists pullout of one or more ring-shaped base members placed over the top of the delineator stem to act as ballast for the delineator stem. The base members include a non-circular raised portion and a correspondingly sized recessed portion such that when one base member is stacked on top of another, the recessed portion of one base member will receive the raised portion of the other base member and resist relative rotatable movement between the base members.
