On both sides, there is a push button installed. When the door closes, the roller pins are moved upwards by a push button action, engaging with the strike plate located in the door frame, and are driven down into the locked position. This pulls the door leaf against the door frame. The eccentric roller pins allow for easy readjustment if necessary. When the key is turned in the opening direction, the main bolt is retracted. A downward push button action retracts the roller pins into the opening position. Subsequently, the latch is retracted.
