European-profile security cylinders, characterized by a universal so-called “European” profile, consist of a one-piece nickel-plated brass body at the center of which rotates a DIN-standard cam moved by the movement of a 14-pin barrel arranged in 3 rows (7 active pins under spring + 7 passive pins) that guarantee more than 2 million combinations. To ensure greater security, the cylinder is not friction-locked, i.e., if the key is inserted into the pawl on the inside, it cannot be opened from the other side. It is equipped with 5 master keys (with orange or blue heads) and 2 yard keys (with black heads). The special feature of the cylinder is that all 7 keys are active, and the two yard keys can be deactivated only by means of a special one/off key.

Thanks to the central reinforcement and to the special pre-cut pre-cut weakening for an early breakage it is ensured an high resistance to the tear. The special spines in tempered steel on the anterior and posterior cylinder allows an high drilling protection while the steel pins and the rust-proof springs allows an high resistance to the abrasion and to the corrosion. The shape pins, besides, allows to prevent the key bumping. The computerized reversible point key, thanks to the long barrel can be used alsowith cylinder protections.
