RSC II adds angle grinder resistance and doubles the test time. It's a real upgrade from RSC I without the cost jump to TL. Here's what it tests, who it's for, and which products carry the rating.
We carry RSC II-rated products from Liberty, Fort Knox, and AMSEC across both showrooms. Most buyers in the Sacramento corridor and Bay Area who have moved past RSC I land here, and most of them didn't know this tier existed before the conversation.

Yes, there is a tier between a standard RSC I gun safe and a TL-rated commercial safe. It is called RSC II, and it is a meaningful step up. The problem is that most buyers never encounter it, the marketing around RSC I safes rarely mentions RSC II, and the conversation about upgrading protection usually jumps straight to TL-rated because that is the only alternative most online content acknowledges.
RSC II tests 10 minutes of combined hand-tool and power-tool attack by a credentialed two-person team. The power tool that matters most is the angle grinder. RSC I specifically excludes power tools. An angle grinder from any hardware store can defeat most RSC I safes in under 2 minutes. RSC II requires that the safe resist the attack for 10 minutes of active working time.
For most Northern California homeowners who have moved past RSC I and do not meet the specific conditions that warrant TL-rated protection, RSC II is the appropriate residential ceiling. It is more expensive than RSC I. It is substantially less expensive than TL-15. And it is the correct answer to the question most people are actually asking when they say they want something more secure than a standard gun safe.
These three ratings cover the range most residential buyers choose within. RSC II is highlighted because it is the tier this spoke covers.
RSC I is the standard most safes ship with. RSC II requires the safe to pass a substantially harder test at the factory level, thicker body steel, heavier door construction, and a lock that meets anti-manipulation standards. The safe you are looking at today is almost certainly RSC I unless the label or specification sheet specifically says RSC II.
A safe that passes RSC II testing is a physically different product from one that passes RSC I. The test is more demanding, which means the safe must be built to withstand a more demanding attack. Three things change meaningfully.
RSC I requires 12-gauge steel as the DOJ compliance minimum. RSC II safes typically move to 10- or 11-gauge steel in the body construction, a meaningful increase in thickness that affects both how the body responds to cutting attacks and how heavy the safe is per cubic foot of interior volume. A thicker body does not stop a sustained power-tool attack, but it substantially increases the time required.
The angle grinder attack targets the door face and the lock area specifically. RSC II-rated safes carry a drill-resistant hardplate protecting the lock, typically a case-hardened steel plate at Rockwell C 60 or harder, and a door construction that slows cutting attack on the face. The door design is where most of the additional material and cost in an RSC II safe appears.
RSC II testing requires the lock to meet anti-manipulation criteria that go beyond RSC I requirements. A UL 2058 Type 1 electronic lock or a UL 768 Group 2M mechanical lock satisfies this requirement. The lock quality step-up is often visible in the product specification; lower-cost RSC I safes frequently carry non-certified or lower-tier locks; RSC II products carry certified lock assemblies.
RSC II is the right product for buyers who have moved past RSC I, who understand that a standard gun safe does not resist power tools, and whose situation does not yet trigger the three conditions that make TL-rated residential appropriate.
The 2025 prosecution documented an organized crew methodology that specifically exploits RSC I construction. For homeowners in the Sacramento suburban ring who have taken that threat seriously but whose collection value does not warrant TL-rated costs, RSC II is the appropriate upgrade. It addresses the angle grinder vulnerability that organized crews leverage against RSC I safes.
Buyers with collections appraised in the $30,000 to $75,000 range, the gap above standard RSC I adequacy but below the thresholds that typically trigger TL-rated insurance requirements, are in the RSC II zone. The protection step-up is real, and the cost increase is reasonable. The insurance implication is worth confirming with your carrier, but RSC II is the right construction floor for this asset level in most NorCal households.
If your insurance carrier has specified a TL rating requirement, if your property is in a rural foothills county with 30-plus minute response times, or if your collection value is at Bay Area asset levels, RSC II may be the right interim product, but it is not the right permanent ceiling. The TL-rated residential guide covers who the TL buyer actually is and what the products look like.
RSC II is not a widely advertised rating. Most manufacturers who have it list it in the product specifications, but the marketing will often just say "UL Certified" or "UL Listed", which could mean RSC I, RSC II, or any other UL standard. The specific rating matters, and it takes one step to verify.
Look for the UL listing label inside the door of the safe. The label references the specific standard met: UL 1037 RSC Level I or UL 1037 RSC Level II. The number is what matters. If the label says Level II, you have RSC II. If it says Level I or just "RSC" without a level qualifier, you have RSC I.
The product specification sheet from the manufacturer should also list the specific certification. "Meets UL standards," "UL quality," or "tested to UL specifications" are not the same as a UL listing. A listed safe has been tested by an independent NRTL and has a serialized listing label. Marketing language that avoids stating the specific standard is not listing language.
Yes. RSC II is a UL-certified rating between standard RSC I gun safes and TL-rated commercial safes. RSC II requires 10 minutes of resistance against a combined hand-tool and power-tool attack, including angle grinders. RSC I requires only 5 minutes of hand-tool resistance. The cost difference between RSC I and RSC II is meaningful but substantially less than the jump from RSC I to TL-15.
RSC I tests 5 minutes of hand-tool-only attack by one technician. RSC II tests 10 minutes of combined hand-tool and power-tool attack, including angle grinders, by two technicians. The construction requirements for RSC II are substantially higher: thicker body steel, a drill-resistant hardplate protecting the lock, and a lock that meets anti-manipulation certification standards. An angle grinder can defeat most RSC I safes in under 2 minutes. RSC II requires the safe to resist that attack for 10 minutes.
RSC II is available from a growing but still limited set of manufacturers at the upper end of the residential market. Liberty Safe, AMSEC, and Fort Knox each offer products at or above RSC II construction. Verify the specific product carries UL 1037 Level II certification before purchasing; the marketing will often say only "UL Certified," which could mean any UL standard. Look for the specific UL listing label inside the door referencing Level II.
For most NorCal homeowners who want protection above RSC I, RSC II is the appropriate ceiling. It covers the angle grinder vulnerability that organized crews exploit against RSC I safes. Buyers whose situation triggers the TL-rated threshold, Bay Area insurance requirements, rural extended response time, or a high-value collection at the higher asset tiers should evaluate TL-15 rather than RSC II as their floor.
RSC II safes span a wide price range depending on size and brand, typically from roughly $800 to $3,000 for quality residential products. Fort Knox, Liberty Presidential and Magnum series, and AMSEC mid-tier products represent the RSC II residential tier. The cost premium over comparable RSC I safes reflects the heavier steel, improved door construction, and certified lock assembly required to pass the test. Confirm current pricing with Norcal at the time of purchase.
We carry Liberty, Fort Knox, and AMSEC products rated at or above RSC II across both showrooms in West Sacramento and San Jose. Most buyers in this tier land on something specific within about 15 minutes of the conversation. Bring the basics: what you are storing and roughly how much of it.
