Not all vaults are created equal. The 9R rating represents the pinnacle of commercial vault security — and understanding what goes into it reveals why your metals deserve this level of protection.
The UL Rating System
Underwriters Laboratories (UL) classifies vault construction on a scale that measures resistance to forced entry:
- Class M: 15 minutes of protection
- Class 1: 30 minutes
- Class 2: 60 minutes
- Class 3: 120 minutes
- Class 9R: The highest rating — resistant to the most sophisticated tools and techniques
What 9R Means
A 9R-rated vault is constructed to resist:
- Cutting torches
- Diamond-tipped drills
- Explosives
- Advanced mechanical tools
- Extended, determined attack
Beyond the Walls
A vault rating is just the beginning. A complete security system includes:
- Multiple alarm systems (motion, seismic, thermal)
- 24/7 monitoring by trained security personnel
- Access controls (biometric, dual-key, timed locks)
- Environmental controls (fire suppression, humidity, temperature)
- Protection through hardened construction designed to withstand forced entry and natural disaster
Why It Matters
Your precious metals represent real, concentrated wealth. They deserve protection that matches their value. A 9R-rated vault is not an expense — it is a guarantee.
