Two independent rating systems
Every safe has up to two separate UL ratings: a burglary rating (resistance to attack) and a fire rating (resistance to heat). They\'re tested separately. A safe can be excellent at one and mediocre at the other. Check both.
Burglary ratings (from low to high)
| Rating | What it means | Typical use |
|---|---|---|
| RSC | Residential Security Container — ~5 min basic attack resistance | Entry-tier home + gun safes |
| RSC II | 10 min attack resistance, harder tools allowed | Mid-tier home safes |
| B-rate | Steel-thickness standard: ½" door + ¼" body | Mid-tier commercial |
| C-rate | 1" door + ½" body | Commercial |
| TL-15 | 15 min against pry tools, hand tools, picking tools | Retail / jewelry / pharmacies |
| TL-30 | 30 min against the same UL tool set | Banks / high-value jewelry |
| TRTL-30 | 30 min against tools + torches (door only) | High-security commercial |
| TRTL-30x6 | 30 min torch + tool, all 6 sides | Bank vaults, casino cages |
| TXTL-60 | 60 min tools, torches, AND explosives | Specialized commercial |
Fire ratings (UL 72)
Fire ratings are expressed as "[duration] @ [temperature]" — e.g., "30 min @ 1200°F." Common tiers:
- 30 min @ 1200°F — typical residential fire safe (SentrySafe most lines)
- 60 min @ 1200°F — mid-tier fire (typical Liberty Centurion / Lincoln series)
- 90 min @ 1700°F — high-tier fire (AMSEC FireBlazer, Browning Hunter)
- 2 hour @ 1700°F — vault-grade (Hollon HS-1750, Brown Safe Vault)
Note: fire-rated safes are not necessarily burglary-rated. SentrySafe units typically have fire ratings but only basic RSC burglary ratings. Match the rating to your threat model.
What rating do you actually need?
- Documents only: 60+ min fire rating, RSC burglary is fine.
- Personal firearms (1-10): RSC II or B-rate, 60-min fire.
- Larger firearm collection: B-rate, 90-min fire, bolt-down.
- $20K+ jewelry / watches: TL-15, 90-min fire, anchored.
- $100K+ contents: TL-30 with TXTL torch resistance, anchored.
- Commercial cash handling: Depending on volume — depository B-rate to TL-30.
- Bank-grade contents: TRTL-30x6 or higher, walk-in vault.
Reading a manufacturer\'s spec sheet
Every reputable safe brand publishes a spec sheet with UL ratings, steel thickness, weight, dimensions, and lock type. Look for:
- UL listing number — verify on ul.com if in doubt
- Door steel thickness vs. body steel thickness (a "1-inch steel door" with ¼-inch body is mostly marketing)
- Bolt count and bolt diameter
- Hinge type (external hinges look strong but can be defeated)
- Relocker — yes/no (a triggered relocker locks the safe when the primary lock is attacked)
- Fire rating duration AND temperature
FAQ
Is a Liberty Centurion 24 really fire-rated?
Yes, but check the specific spec. Liberty Centurion 24 carries a 30-minute @ 1200°F UL fire rating — adequate for documents and most household contents but not equal to a vault-grade 2-hour @ 1700°F unit.
What's the difference between UL TL-15 and TL-30?
15 vs 30 minutes of attack resistance using UL's standardized tool set (hand and pneumatic tools). TL-30 is twice the engineered defense. TRTL-30x6 adds 30 minutes of resistance to acetylene torches across all six sides.
What rating do I need for $50,000 in jewelry?
For $50K+ jewelry/watch storage, minimum TL-15 with B-rate door, ideally TL-30 with a 90-minute fire rating. Insurance companies often offer better premiums for TL-rated storage.
Does my homeowner's insurance care about safe ratings?
Yes. Most policies cap "covered cash/jewelry in a non-rated safe" at a few thousand dollars. TL-15 or higher commonly raises that cap significantly. Confirm with your carrier.
