Do you need more security?
Configuring your lock cylinder to match your requirements
All-round protection as standard

  • The high number of inserted, undivided pin pairs and the use of hardened steel materials protect against the most common opening methods
  • The use of the bumping method (Rapido method) for opening the lock cylinder is not realistic under real-life usage conditions

Even more technical features on request

  • Depending on the requirements, additional security features such as steel reinforcement shims, anti-drill or pulling protection can be selected
  • Dust, insect or weather protection help depending on the installation
  • Different thumbturn knob variants (e.g. design thumbturn knob) and coupling functions (e.g. double key override or priority function) offer even more convenience

Free choice of lock cylinders

The cylinder programme features a wide variety of types to choose from. You can also integrate, for example, cyl for cabinet locks, key-operated switches or lift controls into the system. Choose between various cylinder surfaces to harmonise your design.

Modular construction. Maximum flexibility
Quick and low-cost adaptation

The penta reversible key system offers high levels of investment protection, even when requirements change over the years. 

A modular, upward-compatible system structure allows for quick and easy conversion of the lock cylinders to other lengths and types.
