On both sides, there is a push button. When the door closes, the roller bolts move upwards through a push button action, engaging with the strike plate located in the door frame, and the additional bolts extend. This pulls the door leaf against the door frame. The eccentric roller bolts allow for easy adjustment if needed. A turn of the key will retract the main bolt. The latch and the two roller bolts are now blocked, thus the lock is secured in six points. When the key is turned in the opening direction, the main bolt is retracted. A downward push button action moves the roller bolts into the open position and retracts the additional bolts. Finally, the latch is retracted.
