TUNADOR security doors are completed, according to the series, with two or three independent locking systems, separated from each other – produced by the worldwide leader KALE. They are of exclusive quality and are certified by ISO 9001. The cylinders are solid and with built-in armoured protection against hard drilling instruments of the type "crusher". Steel protective caps provide a high degree of protection against drilling and “bear paw” tools. The installation of concave protective caps prevents power impacts upon them. A new generation of fiseli locks of high security level is also used. A priceless addition to the security is the locking mechanism of the type REVERSE HOOK, peculiar for the doors of the high protection class. For the fans of high technologies the company offers the latest generation locking system with fingerprints, which saves the inconveniences of the use of keys.
