Elegant design with reduced measurements. Made of SUS304 optional SUS316. The tripod rotor is made of steel with an operating life that can reach up to 2 million steps. Anti-overheating mechanism to protect the components that perform the tripod movement even at maximum pitch performance. Anti-panic or emergency arm system, which allows the arm located in the upper part performing the closure, to fold perpendicular to the ground, leaving the passage free for a possible evacuation. But when the electricity returns, the arm must be raised manually. LEDs clearly indicate the direction of passage
