The technical specifications of DU highlight its flexibility and reliability in planning. Its functions, designs, protection classes and materials are consistently tailored to the professional requirements of commercial construction.
The DU system uses several interlocking security elements to provide enhanced protection against tampering. Spring-loaded pivot levers provide a dual security check along the long side of the key profile and are effective against bump picking. This is complemented by lateral coding with variable control pins, as well as a spring-loaded drill and pull protection made from hardened special steel.
Two spring-loaded pivot levers are integrated into one side of the lock cylinder. They perform a dual security check along the long side of the key profile, prevent the cylinder from being turned through and effectively enhance protection against bump picking as well.
On the side of the cylinder core opposite the swivel levers, up to five horizontally mounted, versatile control pins are integrated. This lateral coding provides an additional safety-related check and highlights the technical safety benefits of the DU system.
A spring-loaded locking element made of hardened special steel, housed within the casing, complements the lock cylinder. It performs a contour-based security check on the key and increases resistance to drilling and pulling attempts, acting as an additional effective locking function.

Personalise your locking system and turn it into your calling card. Whether it’s a custom-designed key or a personalised cylinder – CES offers specialist partners a wide range of options for visual and functional customisation. This results in solutions with high recognition value that combine security, brand identity and professionalism, and stand out clearly from standard solutions.
The transponder clip allows CES’s mechanical profile systems to be easily combined with CES’s electronic locking systems and the AccessOne access control system. This creates flexible hybrid solutions that combine mechanical security with electronic organisation. Existing locking systems can be expanded in stages and adapted to new requirements without any disruption to the system and with maximum planning reliability.
