It can also be utilised at outdoor events for crowd control and separating pedestrians from vehicles.

Available in red and white colours, the unique design enables quick and easy fitting, whilst still conforming to the expected standards of a stable fencing system. This product has been tested by MIRA to withstand winds up to a maximum speed of 57mph. Two barriers are required per temporary fence panel.
