Locking system DUplus with 3D key sections
DUplus is the innovative advancement of the proven DU system, based on the tried-and-tested double undercut principle. In DUplus, the undercut is interrupted, clearly visible on the key profile – a key feature for technical protection against unauthorised key duplication.
Inside the cylinder, four additional pins verify the shape and position of the interrupted undercut, providing a four-way profile check that significantly increases the overall security level.
The system was developed for demanding property applications and meets the highest requirements in terms of security, flexibility, and system integration. DUplus supports complex master key systems, is compatible with electronic locking solutions, and available in a variety of finishes and profiles. Whether for new construction or modernisation – DUplus is your long-term, future-proof solution for secure access control.
