In 1907, the imaginative engineer Viktor Gretsch started manufacturing pull-cord fanlight openers, window stays and small fittings. Three years later he made the businessman Johann Maus his partner and Managing Director. The descendants Julius Maus von Resch and Hans Maus advanced the enterprise to an international company. Today, the Gretsch­Unitas Group is managed by the brothers Julius and Michael von Resch in third generation. In the twen­ties and early thirties, the company developed over 120 patents and distributed its successful products throughout Europe. After difficult times, the company was successfully reconstructed and relocated from Stuttgart to Ditzingen. In the mid seventies, the company expanded to a group: first, by acquiring FERCO, the French manufacturer of architectural hardware, later through the acquisition of the leading lock brand BKS and by establishing its own service providers. Thus, a powerful group has emerged with compatible high-quality products and services in the divisions windows, doors, entrance sys­tems and building management. The Gretsch­-Unitas Group consists of more than 50 manufacturing and sales companies in more than 35 countries. With the internationally leading brands GU (architectural hard­ware), BKS (locks, locking systems) and FERCO (architectural hardware), the group offers “Securing Technology for You”. In its divisions of window technology, door technology, automatic entrance systems and building management systems, the GU Group manufactures and distributes about 30,000 single items many of which can be combined with each other easily. With 3,700 employees and over 100 years of tradition, we not only develop single products but complete individual solutions for large-scale projects. Together with architects, planners, and profile system manufacturers we successfully combine visionary architecture and innovative technology. Founded in 1907 by Viktor Gretsch­, the family-owned enterprise is today managed by the brothers Julius and Michael von Resch.
