On both sides, there is a push button installed. When the door closes, the roller pins are moved upwards via the push button action into the locking plate located in the door frame, and the additional bolts extend. This pulls the door leaf against the door frame. The eccentric roller pins allow for easy adjustment if needed. After a key turn, the main bolt is ejected. The latch and the two roller pins are now blocked, thus locking the door six times. When the key is turned in the opening direction, the main bolt retracts. A downward push button action moves the roller pins into the opening position, and the additional bolts are retracted. Subsequently, the latch is drawn in.
