Karl Jindrich significantly extended the product range. EVVA products enjoyed such a good reputation that insurance companies gave a 10% discount on premiums if the doors were protected by EVVA products. The range of key systems was also already very impressive: From ‘single-key’ systems for private households to ‘general master key’ systems for complex facilities and residential complexes, the company offered customised, very high security options. The first large-scale orders came in: the University of Vienna, the local town hall and the Herzmansky department store.
