Highly durable, the Straight Arm / Folding Arm Barrier is both stable and safe to use, coming with a long service life. It is composed of five parts, the cover, housing, transmission unit, control unit, and an arm which can be set on the left or right. Two models of the barrier are available. One is the straight arm with a light belt included at the bottom of the arm, and the other is a folded arm. Both can be used along with a radar to help prevent objects from colliding with the barrier.
