Overview
Locking papers away from fire and flood is what this low, wide SentrySafe is for, with a lid lock meant to stay shut in a fire. Straps inside hold passports and social security cards.
A shallow interior with straps suits flat documents and small cards, and a long water rating gives flood coverage. Fire endurance is limited, and the exterior height is given as two different figures.
Who it's for
Families keeping passports, certificates and A4 papers together at home get a flat, portable box. Anyone who stores bulky items, or wants a longer fire rating, needs a larger safe.
Pros and cons
- Water rating covers long submersion
- Straps hold small cards neatly
- Holds A4 paper
- Tubular key lock
- Fire rating is a half hour
- Exterior height conflicts in copy
- Key lock only
Performance notes
The fire rating limits how long contents are protected at a given temperature, and the water rating applies to submersion for the stated time. The tubular lock holds the lid closed under heat. Interior height limits what can be stored.
