① Sensor type
It is equipped with electronic TOUCH sensor to detect the fingertips and stops the door. It requires expertise in attaching and it is expensive and there is a cause of trouble after mounting.
② Column mounted type

If they are different from each other and there is not a certain gap, it is difficult to construct, and it is difficult to completely prevent the fingers from being caught, and a scratch on the door may occur due to the wear of the door guide.
③ Outside column type (DOOR-based construction)
It is a method of attaching with DOUBLE TAPE using simple JIG to the outside of the door and column. (Easy to install) Even if any condition of elevator door gap (upper, middle, lower part of elevator door gap) Can be prevented.
