Sturdy safe company does not have UL ratings and yet it is supposedly about the best safe on the market. There is a reason why Sturdy safes don't have a UL rating, but the reason slips my mind at the moment.
I was under the impression that Sturdy is moving towards UL ratings in the future?
They likely omit RSC testing because it won't tell their customers anything they don't already know, and the rating could have less insurance value than a tool rating. Sturdy's baseline models are built well beyond what the minimum standards are to qualify for the RSC testing, and their upgraded models can do B-rate, C-rate, and beyond. Unfortunately, there is not a good category between RSC and TL-15, because B-rate and C-rate apply to relatively loose specifications (no one maintains a specific standard, and there are no attack tests to qualify such safes.) I would love to see some type of intermediate category.
The value of the RSC has some other limitations. RSC has occasionally been referred to as TL-5, but this isn't the best term because the RSC attack test uses one man with LIGHT hand tools, where as the TL-15/30 tests involve a two-man team with powered tools and specialty drilling/cutting bits designed to defeat heavily armored safes. With the RSC test, the max weight of hand tools is something like 3 pounds, and I am not sure if the 5-minute test is net tool time or gross time. With TL-rated safes, the number refers to the net tool times...so when changing out tools, examining the attack, or reviewing the building specs of the safe (which the Maker must provide), this is not counted and so a TL-15 test can take several hours. Where as the tool resistant tests are intended to mimic the worst case scenario, the RSC mimics more of a best-case scenario.
A smaller company also may face testing prices that are extremely high. IIRC, UL procedure requires not just a single specimen from the Maker, but one or two additional specimens that the UL can randomly pull from the production line and then test. I believe this applies to BOTH Standard 72 (fire), and 687 (burglary.) However, I am not sure if it applies to RSCs as they use a different standard.
I believe Sturdy is in the middle of that security ratings gap, and that sweet spot of protection + value + quality gives owners options for something greater than a typical gun safe without going to high-security. Sturdy products are oriented more towards the burglary side of the scale, and while the lack of an independent fire rating doesn't mean the safe will necessarily fail to protect the contents in fires, it does mean the outcome is more uncertain. As they continue to grow and testing becomes more financially viable, independent fire ratings could help them grow their brand even further. And as my knowledge in this area is so/so, for what it is worth I also believe that Sturdy is capable of building a safe with a poured composite fire/burglary barrier and delivering it at an affordable price.
Some of my specs might be a bit off, so I apologize if they are.
