The Liberty Magnum 50 in Gray Marble carries the highest fire rating Liberty sells: 150 minutes at 1,200 degrees F as Liberty rates it, backed by 1,585 pounds of steel and insulation. It was $9,939. Now it is $6,999.
Talk to a SpecialistThe word fireproof certifies nothing, which makes it worth dropping before you shop. A fire rating tells you three real things. What interior temperature the safe held, how long it held it, and who ran the test.
Most buyers assume a 30-minute safe and a 2-hour safe behave the same way for the first 30 minutes. They do not. Insulation slows heat transfer from the first second fire reaches the steel, and more insulation slows it more, for the whole event.
Interior temperature after 20 minutes of fire.
Same fire. Same 20 minutes. Same room.
Paper scorches near 350 degrees F. Photographs start degrading around 150 degrees F. Both safes finished that fire inside their rated window, and only one of them gave your photographs a chance.
That is what the minutes actually buy. Not a longer countdown before failure. A cooler interior the entire way through.
The Liberty Magnum 50 is built around that principle. Here is what it actually is.
This is where we point a customer who needs the most fire protection available in a residential safe. Liberty rates it at 150 minutes, and most of its 1,585 pounds is insulation mass and steel.
It sits at the top of Liberty's residential line, and nothing else on our floor outside the commercial vault category rates higher for fire.
You cannot raise a fire rating without adding insulation mass, and mass shows up on the scale. Safes rated at 120 minutes usually land between 800 and 1,400 pounds. This one is heavier than that band.
Fireboard fights heat chemically rather than just blocking it. Under heat it releases bound water as steam, and that reaction absorbs energy the interior never sees.
The gap between door and body is the one direct path from the fire to your contents. The seal expands under heat and closes it.
Boltwork that engages every side keeps the door from bowing as steel expands. A bowed door widens the gap the seal has to bridge.
The rating is only half of fire protection. Where you live decides how many minutes you actually need.
The rating that works in midtown Sacramento is not the rating we recommend in Grass Valley.
A house fire is contained and suppressed, usually inside 30 to 90 minutes of exposure. A wildfire front moves through and keeps burning with no suppression during the event. Customers who lost homes in Paradise, Santa Rosa, and Napa saw safe exposure measured in hours.
CAL FIRE also updated its Fire Hazard Severity Zone maps for Sacramento, Amador, and Calaveras counties in 2025, the first major remapping in over a decade. If your property picked up a new designation, the fire rating math changed with it.
Verified 60 minutes on a concrete surface is a reasonable target for documents. Properties backing onto open space deserve a closer look at their zone.
Mixed contents move you toward 90. Go to 90 if photographs are going in alongside the documents. Concrete placement strongly preferred.
This is a minimum, not a target. Concrete slab placement is required rather than preferred, and clearing fuel around the safe is a real risk reduction step.
Here the safe is one part of the design. Placement and a document backup plan carry equal weight with the rating on the door.

Get a Zone RecommendationA 60-minute safe against an exterior wall with firewood stacked nearby can do worse than a 30-minute safe on a garage slab.
One of our customers lost their home in the 2018 Camp Fire. Their 30-minute rated Liberty safe sat in the debris for 14 hours on a concrete foundation, away from concentrated fuel, and the contents came out intact. The rating gave that safe a chance and the placement let the chance work.
Three Placement Rules We Give Every Fire Zone Customer
A slab holds the safe in place when a structure collapses.
Firewood, gas cans, and vehicles keep feeding heat after the main fire passes.
Sealed closets and understairs spaces hold heat long after the fire moves on.
Yes. The Magnum 50 normally sells at $9,939.00. The promotional price is $6,999, a savings of $2,940. Delivery and installation are quoted on top of that.
It depends on your location and your contents. In urban Sacramento and Bay Area neighborhoods, 60 verified minutes with concrete placement is usually adequate for documents. In foothill and elevated hazard zones such as El Dorado Hills, Auburn, Placerville, Grass Valley, and Nevada City, we recommend 90 to 120 minutes as a minimum. In High and Very High hazard zones, on rural parcels, and near Tahoe, plan on 120 to 150 minutes with deliberate placement.
Yes. Liberty rates the Magnum 50 at 150 minutes at 1,200 degrees F, which is the highest fire rating Liberty sells. It carries a 7-gauge steel body, a 5.5 inch door, up to 18 half-inch locking bars, and weighs 1,585 pounds, which is more insulation mass than most 2-hour safes carry. The rating is paper grade, so photographs and digital files still need separate handling.
A standard fire safe does not. Standard ratings are Class 350, which permits the interior to reach 350 degrees F. Photographs begin degrading near 150 degrees F, and hard drives and flash storage start failing between 120 and 150 degrees F. Protecting those items takes a media-rated safe or a separate backup plan kept somewhere else.
It means the safe was heated to 1,200 degrees F and held its interior below the rated temperature ceiling for 150 minutes. Two numbers matter together, the duration and the test temperature. A 60-minute rating tested at 1,700 degrees F and a 60-minute rating tested at 1,200 degrees F are not describing the same fire, so compare both figures rather than the minutes alone.
Yes. The Magnum 50 weighs 1,585 pounds, so it is a professional installation. Every delivery is coordinated by our team, using our in-house crew or a trusted, vetted delivery partner depending on your location, and they handle stair carries, in-home placement, and floor anchoring across our 17-county Northern California service area. Delivery and installation are quoted separately from the price of the safe.
Yes. Both showrooms carry stock across every brand we sell, and we keep up to 1,000 safes between the two locations. West Sacramento is at 817 Jefferson Blvd and our Bay Area showroom is at 2897 S Bascom Ave in Campbell. Both are open Monday through Saturday, 9am to 5pm.
