Product Details

Do you need more security?
Configuring your lock cylinder to match your requirements

In the penta cross system, there is a cross-shaped recess with a movable active element in the key. When the key is inserted, the movement of the active element is queried by matching security elements in the lock cylinder. The matching lock cylinder can only be locked and unlocked when the movable active element is present in the key.

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 cross 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.
