The Hollon HS-1750C is the flagship of Hollon's HS office safe series. It is a full double-door cabinet sized for the mid-to-large business, legal or accounting firm, or serious commercial operation that needs 20.72 cubic feet of interior storage in a 1,650-pound cabinet and wants the mechanical reliability of a Sargent & Greenleaf Group 2 dial instead of an electronic keypad. Whether you're securing years of client files, legal records, cash bags, jewelry, hard drives, a full firearm collection, or the complete paper history of a growing business, it delivers a 2-hour fire rating at 1,700 degrees Fahrenheit (JIS & GOST certified), an S&G UL-tested Group 2 mechanical dial, 4-way locking bolts with an internal re-locker, and a 1,650-pound cabinet on a 63.50 by 45.71-inch footprint. This is the largest safe in the HS fire-only office series. If you need burglary construction on top of the fire rating, Hollon's FB series adds heavier steel built for burglary resistance.
The interior measures 51.25 inches tall, 38.57 inches wide, and 18.11 inches deep, for a total of 20.72 cubic feet of usable space. That's a substantial jump from the HS-1600C (12.48 cu ft) and nearly triple the HS-1400C (8.74 cu ft), and the double-door design gives you the full 38.57-inch width uninterrupted when both doors are open. Standard 8.5-by-11-inch letter-size and larger legal-size folders lay flat inside with room to spare, and there's clearance for side-by-side hanging file boxes, wide binders, or an organized rifle collection. Interior adjustable shelves let you configure the layout for how you actually use the safe, and key-locking drawers at the bottom of the interior provide separately secured compartments for cash, jewelry, or documents you want protected from anyone who has the safe's combination.
The 2-hour fire rating at 1,700 degrees Fahrenheit is the headline number for this safe, and it is worth understanding. Most consumer fireproof safes are rated for 30 to 45 minutes at 1,400 or 1,550 degrees Fahrenheit. A 2-hour rating at 1,700 degrees Fahrenheit is meaningfully more conservative than the typical residential or commercial fire (which peaks around 1,100 to 1,500 degrees Fahrenheit and is usually suppressed by the fire department within 20 to 30 minutes). That extra margin matters if you're storing genuinely irreplaceable business records, client files, or original documents, if your building has slower fire response times, or if you want your files to come out of a worst-case fire intact. The safe is independently certified to both Japanese Industrial Standard (JIS) and GOST fire testing standards. Construction uses a Portland-cement-based insulation between the inner and outer steel walls, with a grooved door seal that blocks smoke and superheated air from reaching the interior. The HS-1750C is also 30-foot impact-rated, simulating the safe survival of a second-story floor collapse onto concrete during a building fire.
The HS-1750C comes standard with a Sargent & Greenleaf Group 2 mechanical dial combination lock, factory-set with a combination that ships to you with the safe. S&G is the industry-standard lock brand used across banking, government, and commercial safe applications, and Group 2 is a UL-tested lock certification class trusted in commercial vault applications. There are no batteries to replace, no keypad electronics to fail, and no firmware to worry about, which is why many long-term commercial owners specifically choose a dial over an electronic lock. If you'd prefer a digital keypad for faster access and the ability to reset your own code, this same safe is available as the HS-1750E with an S&G electronic lock.
For security, the HS-1750C uses a 4-way locking chrome bolt work system (bolts extend into the top, bottom, lock side, and hinge side of the door frame), plus an internal spring-loaded re-locker that engages if the lock is punched or drilled in a forced-entry attempt. A door detent device automatically locks the safe when the door is closed. Unlike the smaller HS-series office safes, the HS-1750C ships on integrated wheels for positioning rather than a pre-drilled floor anchor hole. At 1,650 pounds, the safe's weight is the primary theft deterrent, and the wheels let you move it into its final position without a forklift. The safe is 30-foot impact-rated and certified to survive the same drop test as the smaller HS-series safes.
On the outside, the safe is 63.50 inches tall, 45.71 inches wide, and 25 inches deep (add 2 inches for the hinges). The wide double-door footprint needs a dedicated wall or office corner with clearance for a nearly 4-foot-wide cabinet and enough swing room for both doors to open. The charcoal finish gives it a clean, professional look that fits in a commercial office setting without standing out as an obvious "safe." Every HS-1750C is backed by Hollon's Lifetime Fire Warranty: if the safe is damaged in a documented office fire, Hollon will replace it. If you have questions about whether the HS-1750C is the right fit for your office, or if you need Hollon's FB series for combined fire and burglary construction, give us a call at 800-207-2259, Monday through Friday, 8AM to 5PM PST. We'll walk you through it.
