Hollon HDS-750C 1-Hour Fireproof Data Media Safe
The Hollon HDS-750C Data Safe is engineered to safeguard delicate digital media—including external hard drives, USB drives, CDs, tape backups, and memory cards—from critical thermal damage. Standard document fire safes keep internal temperatures under 350°F, which easily ruins digital storage media. The HDS-750C maintains an ultra-low interior temperature under 125°F during an external fire reaching 1850°F for a full 60 minutes. Outfitted with a highly reliable S&G Group II Combination Dial Lock, two removable shelves, and 354 lbs of heavy-gauge double-walled protection, this safe provides uncompromising protection against intense heat, sprinklers, water exposure, and ambient humidity.
Key Security & Environmental Protection Features
- 60-Minute Fire Protection for Media: Holds internal temperatures below 125°F during an 1850°F external fire, shielding heat-sensitive digital devices (hard drives, flash storage, CDs, and magnetic tapes).
- S&G Group II Combination Dial Lock: Outfitted with a mechanical Sargent & Greenleaf Group II combination dial lock, offering battery-free dependability and physical security against unauthorized access.
- Water & Humidity Resistance: Sealed double-door construction protects stored media from fire department hoses, sprinkler runoff, and elevated ambient humidity.
- Heavyweight Construction: Weighing in at a solid 354 lbs, it provides significant physical theft deterrence along with thermal mass insulation.
- No Center Bolt-Down Hole: Purposefully designed without bottom floor anchor holes to eliminate pathways for heat, water, and humidity transfer into the internal media chamber.
- Dual Removable Shelving: Includes 2 removable shelves to organize tape backups, hard drive arrays, and camera storage easily.

Frequently Asked Questions
What makes the Hollon HDS-750C different from a standard document safe?
Paper documents withstand heat up to 350°F, but digital storage media begins corrupting and melting at 125°F. The Hollon HDS-750C Data Safe uses specialized double-wall insulation to restrict internal temperatures below 125°F during a 1850°F fire.
What is the difference between the HDS-750C and the HDS-750E?
Both models feature the exact same exterior size (29-1/2" H x 20-3/4" W x 20" D), 354 lb weight, and 1-hour media fire protection. The difference is the locking system: the HDS-750C features a mechanical S&G Group II Combination Dial Lock (no batteries required), whereas the HDS-750E uses an electronic digital keypad lock.
Why is there no center anchor bolt hole on the bottom of the safe?
To preserve strict thermal control under 125°F and prevent water or humidity penetration from sprinklers, the safe is constructed without bottom floor penetrations that would breach the outer protective insulation layer.
Does the mechanical combination lock require batteries?
No. The Sargent & Greenleaf Group II dial lock is purely mechanical, ensuring reliable access without ever needing battery replacements or wiring maintenance.
Can I remove or adjust the interior shelves?
Yes. The safe comes with 2 removable shelves, giving you full flexibility to configure the storage area for tall hard drive towers or stacked backup media trays.
