One Way Flow Plate

This Flow Plate controls traffic flow to one direction only and is designed to work in groups to provide full road width coverage; a three metre wide road would typically require six One Way Flow Plates.

As a vehicle passes over the plate, the flap is pushed down, allowing the vehicle to pass and the rubber buffer on the reverse of the flap ensures noise is kept to a minimum.

Once the vehicle has passed the flap returns to its upright position.

This Plate is constructed from heavy duty steel which is then galvanised to ensure longevity and coated yellow to maximise visibility.

It is not recommended for HGV use.
