Impenetrable AA Roto-Gate

This Roto-Gate is attractive enough to be used in flagship stations but very cost effective. Its average service life at stations is approxi-mately 37 years. It is specially configured to allow transit authorities to provide unattended exits without worrying about vandalism. Its non-welded construction prevents vandals from breaking off arms and its one-way mechanism is simple and immensely rugged. It is available in steel or stainless steel. Other models are available for A.F.C. system control.
