Semi-Automatic Bollards

Designed with simplicity of operation in mind, the semi-automatic bollards contain a gas-filled piston which automatically raises the bollard and locks it into position when the key is inserted. To lower the bollard, the key is inserted to release the lock and then steady pressure is applied to the top. When the bollard is fully lowered, it automatically locks in position. Keys for the semi-automatic series are cut in such a way as to ensure that each is unique in order to thwart attempts at forcing the bollards closed. The piston is engineered to the highest standards and can easily be removed for maintenance. The unit is rated to support 25 tons of pressure from vehicle wheels.
