Patent attributes
A barrier assembly includes a barrier having an interior surface and an opposing exterior surface extending between a first end and an opposing second end. The interior surface bounds a chamber that is adapted to receive a ballast. The barrier also has an internal sidewall extending between top and bottom surfaces of the barrier so as to bound a passage extending completely through the barrier between the top and bottom surfaces. The barrier assembly also includes an elongated coupler extending down through the passage and projecting below the bottom surface of the barrier. A means for securing the coupler within the passage is formed on or attached to the coupler. The means for securing the coupler within the passage prevents the coupler from being removed from the passage while allowing the coupler to freely rotate within the passage.
