The TrafFix Devices Tire Ring Base is made from truck tire sidewall sections. It's economical and easy to use and provides all the ballast you'll need to hold a drum in place, even in the windiest conditions. The tire ring eliminates the need for sandbags that tear or break leaving messy sand on the roadway. The rubber tire ring "grips the road" and minimizes drum movement and rotation.
Each TrafFix Devices' patented drum has two molded-in, Anti-Rotation Ribs to hold a tire ring securely in place.
TrafFix channelizer drums (with tire rings) have been impact tested under the direction of NTPEP. The TrafFix drum top successfully separated from the base when repeatedly impacted by the test vehicle in both warm and cold weather tests.*
Remember, by using truck tire sidewalls for channelizer drum ballast, we are reusing truck tires and helping to keep them out of landfills.
