RONIS C4 Robust mechanical combination lock


The C4 combination lock is ideal for use in schools and workplaces. The simple design and comfortable, easy grip make it an ideal solution for settings with children or students.

The intelligent design ensures the C4 can be retro fitted onto almost any existing locker. They are also cost-effective because they eliminate the need for keys and the additional hazards associated with losing and replacing them.

The combination lock is fitted with a settings button for reprogramming the device. Users can then set and change codes with a possible 10,000 combinations quickly and easily on site. Fitted with a patent protected detector plate, forgotten codes can be identified in seconds using just the reset key.
