The locking-system 2500 is a revolutionary innovation in the field of swing-handles. The handles are modular and support a wide range of locking sets. Equipped with an electronic locking-module, it is possible to integrate the handle into a monitoring-system for IT installations such as server-cabinets. The design is easily adaptable to customer-demands due to the platform-strategy of the system. The locking technology is covered by several pending patents.
