The Road Rock is a multifunctional base weight, allowing temporary barriers to withstand Class B Wind Speeds (17.6m/s). When the barriers are in a boxed formation, only a single Road Rock is needed per barrier to pass Class B. The Road Rock is a great solution to sandbag filled ballasts, resulting in a clear workspace.
The Road Rock consists of a hook and tail connection similar to the Road Runner, making it possible to create a continuous run. The Road Rock has a center slot which allows a twist-to-rock cylinder to be attached.
The Road Rock can be embossed with a corporate logo, is stackable, and weighs 15kg. The Road Rock consists of 100% recycled PVC, which is also 100% recyclable.
