Construction and protection design
The C40 is manufactured from high-resistance steel sheet and engineered for robust structural integrity. The door is reinforced and designed with solid locking bolts and protective elements intended to increase resistance against common forced-entry methods. This construction approach is particularly relevant for users who want a compact safe with a high “weight-to-volume” ratio and a strong mechanical baseline.

The C40 is supplied with a twin-key locking configuration as standard, with additional locking options available depending on the access policy and usage frequency. Typical specifications include:
- Mechanical combination lock
- Electronic lock
- Biometric lock (selected configurations)
- Dual-control configurations (e.g., key + code) where required
Interior configuration
- Fixed or removable shelf options
- Optional internal cash box
- Optional accessories depending on project requirements
Finish and installation
- Finish: polyurethane paint, textured dark grey (RAL 7024)
- Prepared for anchoring (floor or wall) to reduce removal risk
For best real-world security, anchoring to a suitable structural substrate is strongly recommended. Correct fixation and placement are key factors in preventing removal and improving practical performance.
Where the C40 fits best
- Homes: passports, certificates, jewellery and emergency cash
- Small offices: sensitive files, small valuables and controlled-access items
- Secondary locations: discreet storage where space is limited
