Six criteria. Ten levels. Every safe Norcal carries scored on a single transparent scale, no manufacturer marketing language required.
UL ratings, TL ratings, RSC ratings, and brand claims use incompatible scales that cannot be compared directly. The Norcal Security Level System converts all of them into one consistent framework, scored across six construction criteria by the team that sells and installs every product on this list.
No other dealer in Northern California has published an equivalent scoring framework for their own lineup.
The problem with safe comparison is that no two rating systems speak the same language. A UL RSC I rating and a TL-15 rating measure different things at different thresholds. A manufacturer's fire rating may or may not be independently certified. An electronic lock may carry a UL 2058 certification or none at all. Comparing two safes across these systems requires translation work that most buyers cannot do and most retailers will not do for them.
The Norcal Security Level System resolves this. Every safe Norcal carries has been scored across the same six construction criteria on a 15-point scale. The weighted total produces a single score that places the safe on a 10-level scale, from Level 1 (Basic Security) through Level 10 Security. Any two safes in the Norcal lineup can be compared directly on this scale without needing to translate between rating systems.
As Liberty's #1 dealer in the country for 30 consecutive years and a top-dealer partner with AMSEC, Norcal has the product depth to score credibly across every tier, from entry-level residential to TL-30X6 commercial-grade. No other regional dealer has an equivalent published framework applied to their own lineup.
Every safe is scored on six independent criteria. Each criterion is rated from 0 (not present or not certified) through 15 (top available performance in that category). The six scores are weighted and combined to produce the overall Security Level score.
The gauge and quality of the body and door steel, the structural foundation of the safe.
The lock's certification tier, UL Group 2, Group 2M, or UL 2058 electronic, and its manipulation and attack resistance.
The certified fire rating duration and whether it was independently tested (UL 72 or ETL) rather than self-described.
Overall mass and composite layering, the thickness and weight that translate to real pry and attack resistance.
Third-party verification: UL RSC, TL-15/TL-30, UL 72, and ETL ratings tested by an accredited laboratory.
Relockers, hardplate, spring-loaded backups, and bolt work that extend resistance beyond the primary lock.
The weighted total of all six criteria produces a score between 0 and 15. That score maps to one of ten security levels. The level name and score range tell you where the safe sits relative to everything else in the Norcal lineup.
Entry-level residential protection — the floor of the scale.
Strong fire and security protection for significant collections and high-value residential assets.
TL-rated, commercial-grade construction — the highest level in the Norcal lineup.
Note: only Levels 1, 5, and 10 are defined in the current wireframe. The intermediate level names and score bands are pending the full scale definition.
Scoring data pending. The wireframe does not include the 31-model dataset (per-criterion scores, overall totals, and assigned levels). The table structure below is built and ready; rows populate once the content team delivers the model scores.

Every brand in the table above uses a fixed-specification model. The product you choose determines your security level. Fort Knox uses a different approach. Their safes are built on a heavy domestic steel platform, and the buyer selects the lock certification, door construction, relocker system, and fire package. The security level is determined by what you specify, not by which product is closest to what you need.
Because of this, Fort Knox cannot be scored as a fixed entry in the table. A base configuration enters the scoring system at Level 7. Fully specified models reach Level 9 and Level 10. The same model family spans that range depending on the options selected.
The Security Level System is the output stage of the 4-Priority Framework. It converts your protection level requirement into a specific product comparison. Once you have established your capacity, your asset value, and your protection tier, the scoring table tells you which models meet that tier and how they compare to one another within it.
The NorCal protection level guide maps your asset value, location threat environment, and any insurance requirements to one of four tiers: Standard Residential, Elevated Residential, High-Security (TL-15 / TL-30), and Vault-Level. That tier is the target level group you'll look for in the scoring table.
Find your target level group in the scoring table and compare the models within it. Models at the same level have roughly equivalent overall scores. Their individual criterion scores may differ. If you have a clear target tier, compare only the models within that level group.
If fire protection is your primary concern (FHSZ-mapped property, foothills location), prioritize the Fire Protection criterion score within your target level. If burglary resistance drives the decision, prioritize the Steel Construction, Build Density, and Independent Certifications scores within that same level instead.
The scoring table tells you what the safe measures. The showroom tells you what it weighs, how the door swings, and how the interior configuration compares to your actual storage needs. The scoring table narrows the field; the showroom confirms the final choice.
If you've used the 4-Priority Framework to identify your protection level, the Security Level System is where that output maps to specific models. It's the translation layer between what you need and what you should be looking at.”
Norcal Safe & VaultThe Norcal Security Level System is that framework. UL RSC ratings, TL ratings, fire rating durations, lock certifications, and manufacturer claims all use incompatible scales. The Security Level System scores every safe Norcal carries across six standardized criteria and produces a single weighted score on a 10-level scale. That lets you compare any two safes in the Norcal lineup directly, without translating between rating systems.
The score represents the weighted total across six construction criteria, each scored 0 to 15: steel construction quality, locking mechanism certification, fire protection rating, build density, independent certifications, and additional security features. A Level 1 safe scores between 0 and 6.5, increasing through the scale to Level 10, which represents TL-rated, commercial-grade construction. A higher level means stronger, better-certified construction across the six criteria.
Three full levels of protection across all six criteria. Level 5 safes score between 9.51 and 10.0. They carry strong fire and security protection appropriate for significant firearms collections and high-value residential assets, but without the construction density and certification depth of the upper levels. A Level 8 safe scores meaningfully higher across steel construction, build density, and independent certifications, placing it closer to high-security, TL-rated territory.
Each safe is scored across six criteria by the Norcal team: steel construction, locking mechanism quality, fire protection rating, build density, independent certifications, and additional security features. Each criterion is rated from 0 to 15. The six scores are combined using a weighted formula to produce an overall score, which maps to one of ten security levels. The scoring is done by the same team that sells and installs every product in the lineup.
Yes, that's its primary purpose. Comparing a Liberty Colonial to an AMSEC BFS Series using the manufacturers' own specifications requires translating between incompatible rating systems. The Security Level System scores both against the same six criteria, producing directly comparable scores. The Colonial and the BFS Series can then be placed side by side on the same 10-level scale, so you can see exactly how they differ in steel, lock, fire, density, certifications, and features.
