An unbolted safe is a strongbox with a handle for carrying it away · review
The only safe on this shelf with an alarm — three wrong codes and it sounds — and the only one that lists every item in the box.
The conclusion The only safe on this shelf that makes a noise when somebody gets the code wrong three times, which is the one feature here that turns a quiet attempt into a noticed one — and the only one that lists everything in the box, batteries included. Two steel bolts, two ways in, a removable shelf and masonry screws for fifty-five dollars. No internal dimensions, so the shelf clearance is a guess, and no thickness or grade.
No internal dimensions. No thickness. No grade.
Three wrong codes, and noise.
A small safe is opened by someone with time and privacy. What defeats both is being heard.
Three attempts is the right threshold: enough for a user who has forgotten which code they set, too few to work through combinations.
It runs on the same four AA cells as the keypad, which is worth remembering.
Including the batteries.
Two keys, four AA cells, a felt pad, two expansion screws.
Several electronic safes on this shelf need four cells that are not supplied, which is a locked box until you find them.
The felt pad goes in the base: it stops the contents rattling and the safe scratching a shelf.
Which takes paper flat.
The 0.23 cubic foot cubes in this group are 9 inches across and make you fold documents.
What the page does not say is how tall each half is with the shelf fitted — and that is the figure this shelf’s buying tip asks for.
On sale at around $55 on the American Amazon store at the time of checking.

It sounds after three consecutive wrong codes, which changes the arithmetic of a casual attempt. Most small safes are opened by someone with time and privacy — this shelf's introduction makes that point about portability — and the thing that defeats time and privacy is noise. Three wrong entries is also a sensible threshold: enough for a legitimate user who has forgotten which code they set, few enough to stop anyone working through combinations. It is the only alarm published on this shelf, and it runs on the same four AA batteries as the keypad.
Because it is the difference between a safe you can install this evening and one that needs a trip to a hardware shop. Two keys, four AA batteries, a felt pad and two expansion screws is the fullest list in this group, and the batteries in particular are worth noticing: several electronic safes on this shelf need four cells that are not supplied, which is a locked box until you find them. The felt pad is for the base, to stop the contents rattling and the safe scratching a shelf.
It is the middle of this shelf — bigger than the 0.17 to 0.25 cubic foot boxes and far smaller than the 1.8 and 3.4 cubic foot cabinets — and at 13.8 inches wide it takes documents flat, which the small cubes do not. What is missing is the internal measurement: with a removable shelf fitted, the question is how tall each half is, and the page does not say. This shelf's buying tip is exactly about this, and this listing gives you the outside and not the inside.
