    摘要: Plastic fencing has a plurality of openings therein and one or more strips of reflective tape applied to one or both sides of the fencing to make the fencing more visible under poor lighting conditions as when used as a visual warning barrier around construction sites and the like. To secure the reflective tape to the fencing, the reflective tape is adhered to one side of the fencing in overlying relation to some of the openings therein, and to a plastic backing applied to the opposite side in line with the reflective tape through the openings in the fencing.

    摘要: 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.
