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.
