Polish Combination Lock (PCL) unique features are:
- Complete separation between Combination mechanism movement and Opening mechanism movement (no physical touch in close state – air gap marked red arrow below). The attacker can rotate 360 degree all knobs without the change to “fill” the mechanism and to crack it.
- You can set up combination only if you do not try to open at the same time
- If you try to open then you can’t change the combination at the same time
- You can try only one combination at the same time
- Secure Close and Secure Open position possible (picture below – the arrows indicate secure open and secure close position, it can be right or left oriented)
- Full range of possible combinations = You can set i.e. all the same numbers
- Combination change if needed.
- Unlimited numbers of combination wheels = maximum security
- Flexible number of possible combinations on each wheel (it could be i.e. 20 or 100 numbers per wheel)
- Unique actuator design depends on application: padlock, safe lock, door lock
- Padlock can be fully assembly and disassembly without tools and easy to maintenance
- No springs in the mechanism – important feature – long lasting mechanism
- In the final production version the mechanism must be protected against drilling by adding anty-drill discs inside the mechanism covering the internal wheels
