Fencing Barrier Gates are used to stop people going from beneath the boom. It is mainly used to prevent people from tress passing using cycles etc (as mainly done in railway crossing). Typical boom barriers only come with a boom (rod) that prevents vehicles from passing. However, pedestrians can easily bypass the system by jumping over the boom or by going under it. Fencing barriers act as a ‘fence’ by not only keeping away the vehicles but also pedestrians. People with bicycles, people on foot,
both are prevented from going past the barrier. When the barrier opens, the fence collapses and folds neatly. When the barrier is closed, the fence is brought down again.
