Protect vital personal documents, passports, land deeds, cash, and small valuables against severe house fires and water exposure with the heavy-duty Hollon HS-310D Compact 2-Hour Fire Safe with Dial & Key Lock. Built with a seamless body and extra-thick wall construction, this compact 0.53 cubic foot vault delivers an extraordinary 2-hour 1850°F fire endurance rating, advanced grooved smoke and water resistance, a precision mechanical 4-number combination dial lock, and a secondary high-security key lock for convenient day-lock operations.

Key Features & Performance Highlights

  • 2-Hour Certified Fire Protection: Tested to withstand extreme thermal exposure up to 1850°F for 120 minutes, maintaining internal vault temperatures well below document damage thresholds.
  • Grooved Door Seal Design: Engineered with a specialized grooved door jam that creates a barrier against heat, smoke, and water entry during firefighting efforts.
  • Seamless Body & Door Construction: Seamless wall construction increases structural strength, aesthetic appearance, and defense against impact and leverage attacks.
  • Mechanical Combination Dial & Secondary Day Lock: Uses a 4-number mechanical combination dial lock paired with a high-security key lock that can be used independently as a day lock while the combination dial is left set.
  • Heavy-Duty Rectangle Bolts & Deadbolts: Features 2 active rectangular solid steel locking bolts on the opening side paired with fixed hinge-side deadbolts to secure the door firmly into the outer casing.
  • Removable Slide-Out Top Drawer: Equipped with a convenient top pull-out tray to keep cash, coins, jewelry, and passports organized above larger items.

Frequently Asked Questions

How does the key day-lock feature work on the Hollon HS-310D?

The key lock works in tandem with the mechanical combination dial. Once the dial combination is correctly entered, you can turn and remove the key to lock the safe for temporary daytime access without needing to re-dial the full combination sequence every time you open it.

What is the difference between the Hollon HS-310D and HS-310E?

Both safes share identical 2-hour 1850°F fire ratings, outer dimensions, weight, and interior storage options. The HS-310D features a mechanical 4-number combination dial lock with a secondary key day-lock, whereas the HS-310E features a digital electronic keypad lock.

Is the Hollon HS-310D water and smoke resistant?

Yes. The HS-310D features a specialized grooved door design that forms a protective seal against water intrusion and smoke during firefighting efforts.

Can the keys be duplicated at a regular hardware store or locksmith?

No. The safe uses high-security keys with specific identification numbers stamped on both the lock face and key. Duplicate keys must be ordered directly through authorized Hollon dealers using the unique key code.

How is the safe mounted to the floor?

The safe features a factory pre-drilled anchor hole located in the bottom of the casing and includes concrete anchor bolts to mount the 81 lb unit directly to concrete slab foundations or wood subfloors.
