In financial security, cash box locks must provide both security and usability. Disc detainer locks are preferred for their structural advantages, but their quality varies significantly in the market:
Security Risks: Non-certified locks have a mutual opening rate of up to 1 in 50, which is significantly higher than the C-level standard (≤1 in 50,000).
Cost-Effectiveness: C-level disc detainer locks are only 15–20% more expensive than B-level locks, yet they provide 10 times greater resistance to lockpicking.
Adaptability: Key mechanical parameters, such as cash box thickness (8–15 mm) and installation aperture (Φ12–16 mm), must be taken into account.
Certified to C-Level under GA/T 73-2015 'Mechanical Anti-Theft Lock' by the Ministry of Public Security, with a lockpicking resistance of ≥15 minutes and physical destruction resistance of ≥30 minutes.
