Auxiliary security locks
Open the door in a secured position thanks to an extra-strong door limiter
Opening in a secured position
An auxiliary security lock is particularly suitable for older people and households with children: you can open the front door a crack while it stays secured. That way it cannot be forced open from outside.
The integrated door restrictor, the restrictor bar, does not latch when you open the door. In a dangerous situation, you can close the door again quickly.
Two locking points
The auxiliary lock is a further effective way of securing your door, because its keeper also holds a cylinder. This means you lock your door at two points. If you wish, both cylinders can be operated with the same key.
