The PF5800 Range of one way flow platesare designed to encourage mono-directional traffic flow control, whilst also acting to deter unauthorised access by vehicles entering areas via the wrong direction, i.e. entering by way of an exit route or exiting by way of an entrance.

Constructed from robust heavy steel plate, a sophisticated in-built counter balance or heavy duty spring action ensures that the PF5800s return to their upright position after a vehicle has passed over it.
