C-Level Certified Disc Detainer Locks: Ultimate Guide for Cash Box Security

I. Key Factors to Consider When Choosing Cash Box Security Locks

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.
