ABSTRACT:
Traffic channeling device includes a deformable plastic drum and a rubber collar insertable over the drum to act as ballast for the drum. The rubber collar comprises a bead portion and an integral side wall portion of a recycled truck tire. When the rubber collar is inserted over the drum, the rubber collar gives the drum a relatively low center of gravity and grips the ground over a relatively large surface area to resist tipping of the drum and eliminate walking of the drum on the ground.
