Lane Changer traffic drums feature a superior stacking height design to maximize load quantities per truck, thus allowing you to get more drums to the jobsite in fewer trips. The drum’s four 5-in.-wide anti-rotation claws grip the tire ring to keep the drum facing traffic. The drums meet MUTCD and NCHRP 350 requirements. Sheeting configurations are available to meet all state specifications. No other traffic drum stacks up as well.
