Traffic - Line Gamma 20mph Modular Speed Table L4000(mm) x W2700(mm) x H80(mm) - Black/WhiteThis Extra Large modular speed table from the Traffic Line range is designed to span the entire carriageway on one way systems, ensuring that all vehicles, from cars to trucks and buses, slow to a safe speed in pedestrian heavy zones. Available in a range of kitted sizes, this ramp is designed to go as close to the kerb, or to the centerline of the road, as possible. This ensures all traffic is slowed, yet still allows water to drain past on the kerb
