RONIS C4-MU Robust mechanical combination lock public mode


The RONIS C4-MU combination lock is ideal for areas open to the public. The simple design and comfortable, easy grip makes it an ideal solution for culture, leisure and sport environments.

The intelligent design ensures the C4-MU 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.

Users can set codes with a possible 10,000 combinations quickly and easily on site. The dials automatically return to 0-0-0-0 once the lock is engaged for maximum security. Fitted with a patent protected detector plate, forgotten codes can be identified in seconds with just the reset key.
The lock automatically resets when the right code is set again and the knob turned back in its initial position.
