Vector profil rib
The vector profile rib has a high-quality rib profile with six active spring-mounted pin tumblers. The profile match of the key is arranged parallel to the back of the key. The respective profile characteristics are arranged horizontally in pairs and at an angle to each other and form matched pairs. Manual opening techniques are severely hampered with this special arrangement. A shape scanning pin in the locking cylinder also checks the encryption on the key. An additional locking pin queries the one-sided rib. In comparison with conventional key profiles, it is distinguished by high security against breakins, scanning and lock picking.
