At 37-inches tall with a 23-inch diameter recycled rubber base, our plastic drum channelizer barrier exceeds standard safety dimensions. Known also as highway barrels, road drums, channelizer drums, highway drums, or traffic drums, these are made from lightweight polyethylene while the hefty base is composed of recycled tires so no additional ballast is needed. Even if it does tip over, it’s unique shape inhibits it from rolling into traffic. Ideal for freeways, interstates and other high speed roadways. Bold, UV-resistant orange with 4-inch orange and white reflective stripes on engineer grade and high-intensity grade sheeting. Channelizer drums support use of Type A or C barricade lights which can be mounted on top for added visibility. Tapered design makes for easy stacking. Ships immediately. Meets NCHRP 350 TL-3 crash test standards.
