Our range of series 3 cylinders has expanded thanks to the introduction of the shaped cylinder with CLUTCH-TYPE CAM.

The series 3 cylinder with clutch-type cam is equipped with an internal telescopic joint.

This special mechanism, designed specifically for series 3, allows to open the door even if the key is already inserted from the inner side.

This function is also called EMERGENCY FUNCTION because it allows the person with the key to open the door in any situation, even in the event of someone forgetting the key inserted into the cylinder from the internal.
