UL 2-hour fire and B-rate burglary: a safe within a safe
Built for owners who want layered protection in a compact footprint, the Gardall Z-1818 Combination Security Fire & Burglary Chest pairs a B-rate inner burglary chest with a UL-labeled 2-hour fire body rated to 1850°F. It carries a UL Residential Security Container burglary listing, a UL Group II combination lock, and is hand-built in Syracuse, New York.
The Z-1818 measures 25 inches high by 17.25 inches wide by 25.75 inches deep and weighs 455 pounds. Inside, the main fire chamber offers 9.75 by 11 by 14 inches (about 0.87 cubic feet), while the bolted inner chest adds a separate guarded compartment for your highest-value items.
Engineering & Security
- B-rate burglary chest: A bolted inner chest with a triple boltwork door and relock device adds a second guarded layer inside the fire body.
- UL Residential Security Container: The outer door carries a UL RSC listing, verified against hand-tool attack with full technical drawings of the safe.
- UL Group II combination lock: Spec includes a UL-listed Group II high-security lock with a built-in relocking device; mechanical or electronic options are available.
- Hard plate and locking bar: Interlocking exterior bolts, a full-length hinge-side locking bar, and a drill-resistant hard plate protect the lock and boltwork.
- Made in the USA: Each chest is hand-built at Gardall's plant in Syracuse, New York, one of few US safe foundries.
Fire Protection & Interior
- UL 2-hour fire label: Carries a UL 2-hour 350° fire and impact label, furnace-tested to 1850°F for two hours.
- Sub-350°F interior: During testing the interior stayed below 350°F through the burn and cool-down, the threshold protecting paper documents.
- Layered interior storage: The 0.87 cubic foot main chamber plus a separate inner chest let you sort documents from valuables behind two barriers.
Ideal Buyer & Use Cases
The Z-1818 suits homeowners and small businesses who want both UL 2-hour fire protection and a B-rate burglary chest in one 455-pound unit measuring 25 by 17.25 by 25.75 inches. Its safe-within-a-safe design fits cash, jewelry, and irreplaceable documents that warrant two layers.
If you need less interior room, the smaller Gardall Z-1812 is a step down; for more capacity, look to the Z-2218 or larger Z-3018 in the same combination security chest line.
