An unbolted safe is a strongbox with a handle for carrying it away · review
The only small safe on this shelf built as a double wall with insulation between — and the only fire claim here without a duration.
The conclusion A double steel wall with fire-resistant insulation between it is the right way to build a fire box, and nothing else small on this shelf is built that way — with a key lock, a reinforced hinge and a padded floor, for thirty-one dollars. What is missing is the number that makes a fire claim mean anything: no duration, no certifying body. No dimensions either, and nothing about anchoring, on a box the listing sells as portable.
No fire duration. No certifying body. No dimensions. No anchoring. No grade.
Two skins, insulation between.
The insulation releases moisture as it heats, holding the inside below the temperature at which paper chars.
It is why fire safes weigh several times what a plain steel box of the same size does — and why 0.17 cubic feet is the smallest capacity in this group. Some of the difference is wall.
At least eight of the seventeen safes here are single-skin steel, with no fire protection at all whatever their bolts.
Which is the number the claim needs.
SentrySafe, on this same shelf, states UL thirty minutes on its document chest and two hours on its cabinet.
This says fire-resistant insulation. Read it as a description of the construction, not as a promise about time.
Which the shelf’s own introduction warns about.
Easily portable, lightweight, ideal for securing essentials on the move.
A safe which is not bolted down is opened at leisure somewhere else.
For passports and a phone in a house where the threat is a kitchen fire, that is still a sensible thirty-one dollars.
On sale at around $31 on the American Amazon store at the time of checking.

The page does not say, and that is the figure a fire box exists for. It states double steel wall construction with fire-resistant insulation, which is the correct way to build one — the insulation releases moisture as it heats and holds the interior below the temperature at which paper chars — and it gives no duration and names no certifying body. SentrySafe, on this same shelf, states a UL thirty-minute classification on its document chest and two hours on its cabinet. Treat an unrated fire claim as a construction description rather than a promise.
Two skins of steel with insulating material between them, rather than a single skin. It is how every genuine fire safe is built, and it is why fire safes weigh far more than plain steel boxes of the same size. On this shelf it separates this box and the SentrySafe products from the eight single-skin steel safes, which offer no fire protection at all whatever their bolts. The cost is interior space: 0.17 cubic feet is the smallest capacity in this group, and some of that difference is the wall.
It is not sold to be, and the listing sells the opposite — easily portable and lightweight, ideal for securing essentials on the move. This shelf's introduction is firm that a safe which is not bolted down is portable and a portable safe is opened at leisure somewhere else, so read this as fire protection with a lock rather than as security. For passports, a birth certificate and a phone in a house where the realistic threat is a kitchen fire, that is a sensible thirty-one dollars.
