Product description

• A handle is mounted on both sides. A roller face plate with roller pins is also mounted. Once the door falls shut, the roller pins are moved upwards into the locking position in the striking plate in the door frame via an upwards handle movement. This pulls the door leaf to the door frame. Turning the key in locking direction extends the main bolt. During locking, the roller pins move down into the striking plate via a downwards handle movement in open position. Turning the key in opening direction retracts the main bolt.
