1. A base unit for a traffic delineating device, comprising a molded plastic body, having similarly shaped generally parallel
upper and lower surfaces, and an integral outer wall connecting said upper and lower surfaces and extending around more than
180 degrees of an outer periphery of said upper and lower surfaces to space said upper and lower surfaces at a distance B
from each other, wherein:
said outer wall extends around not all of said periphery, thereby leaving an opening between said upper and lower surfaces
to permit insertion of ballast means into said body;
said upper and lower surfaces each have a similarly shaped generally central hole for said traffic delineating device to project
upwardly therethrough, said central holes being generally vertically aligned with each other; and
said upper and lower surfaces each have at least one non-round portion extending to said periphery.
