Why buy from T.D.I.?
Since 1987, TrafFix Devices, Inc. has been providing their customers with the most value for their channelizer drum dollars. The drum tops and bases we made in 1987 are still interchangeable with our current production model.
At TrafFix Devices, we use only the highest grade plastic resins to manufacture our drums. Our drum tops and bases are designed to "break-away" rather than "break-apart" upon impact.
