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 national testing organization. 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.
*Test and evaluation results are available from AASHTO's (American Association of State Highway and Transportation Officials) national transportation product evaluation program (NTPEP) director. Products were field tested and evaluated by NTPEP as described in the work plan for temporary traffic control devices. NTPEP is supported by the 52 AASHTO member departments.
Note: All channelizer drum tops illustrated on this page can be ballasted with tire rings. Tire size should be 22.5" (nominal diameter).
