The additional door lock 2130 from Abus is suitable for installation on inward-opening entrance doors and is equipped with a sturdy locking bracket for a gap-wide opening of the door. It is operated from the outside with a key included in the scope of delivery and from the inside with a rotary knob. Thanks to the solid fastening and the 5-pin precision cylinder, the two-turn additional lock offers effective protection against the door being forced open. The additional door lock 2130 from Abus is adjustable and can therefore be mounted on both the left and right side of the door.
