Height barrier with locking and opening control system from the hinge post. Our unique design designed and developed by our in house design team has been developed for customers who have health and safety issues on busier sites. The barrier offer a low level lock that is control by a winching mechanism. The barrier arm can be opened and closed at the hinge post, this means that there is no need for users to have to cross a busy road to unlock and open or close their barrier. This barrier has proven to be a favourite at Amazon depots and larger busier car parks where health and safety is a real concern.
