NJ GATE
描述
Sliding Gate Systems are the most secure automatic gate systems around, as due to their operation and positioning, when closed they are almost impossible to open. They are held in place by the tracking system, drive motor, and other features of the installation, such that they cannot be wedged sideways except by very unusual and extreme force.
