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. 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 expert plus 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.

The existing lock cylinder can be adapted to a new length with little effort, for example for a new entrance door, or can be fitted with an elegant thumbturn knob.
