The NS131052B001G02 is a precision-engineered door coupler (commonly known as a "door knife") used in elevator systems to synchronize the movement of the car door with the hoistway doors. This component features a dual-claw mechanism that engages precisely with the hoistway door lock rollers when the elevator is leveled, creating a reliable mechanical linkage.
