Channelizer Barrel is the tallest, most visible barrel available out on the market today. The barrel features a molded in handle with holes for mounting a light, 5-tiers for reflective material and a unique anti-roll base. Ballasting the Channelizer couldn't be easier. Just fill the base with up to 50 Ibs. of sand, insert the plug and snap on the barrel. The positive locking base prevents any kind of premature separation while setting up.
