Hollon B3500 Floor Safe

B-Rate in-floor concealment: a hidden anchor for cash and valuables

For homeowners and small businesses who want valuables hidden below the floor, the Hollon B3500 Floor Safe is a B-Rate in-ground safe built around a 1/2-inch solid steel door. Once set in concrete and covered by carpet or a rug, it stays out of sight, and its five chrome-plated steel locking bolts and UL Listed Group II dial lock resist prying. Origin is imported.

This is a compact in-floor model: external dimensions are 18 inches high by 23.5 inches wide by 13.5 inches deep, with a 16.5 by 23 by 13-inch interior, and it ships at 125 pounds before concrete installation. The footprint suits coins, jewelry, paperwork, and cash within an existing slab or poured-concrete pour.

Engineering & Security

• ✓B-Rate burglary classification: Hollon rates this floor safe B-Rate, denoting a 1/2-inch door and reinforced body intended to slow forced and pry attacks.
• ✓1/2-inch solid steel door: Half-inch plate steel forms the lid, the primary barrier a thief must defeat once the safe is located underground.
• ✓Five chrome-plated steel locking bolts: Multiple solid steel bolts plus a full-length dead bar spread clamping force across the door to resist prying.
• ✓UL Listed Group II dial lock: The mechanical dial carries a UL Listed Group II rating, a serviceable high-usage lock with no batteries to replace.
• ✓Drill-resistant hard plate and relocker: A hardened hard plate shields the lock from drilling, and a spring-loaded relocking device fires if the lock is punched.
• ✓Not fire-rated by design: This is a burglary floor safe with no fire rating; store irreplaceable documents in a separate fire-rated container.

Concealment & Installation

• ✓In-floor concealment: Set into concrete and covered with carpet or a rug, the safe is difficult to find and harder still to remove.
• ✓Concrete anchoring: Encasing the body in a slab makes extraction impractical, since a thief must break out the surrounding foundation to reach it.
• ✓Compact 125-pound body: At 125 pounds and 18 by 23.5 by 13.5 inches, it fits a poured pocket in residential or light-commercial floors.
• ✓Spring-assisted lid and turn handle: A chrome turn handle and lift-assist make daily access from above straightforward once the safe is installed flush.

Ideal Buyer & Use Cases

The Hollon B3500 fits homeowners and small businesses that want a concealed, B-Rate floor safe for coins, jewelry, cash, and paperwork rather than long guns. Plan for professional concrete installation; external dimensions are 18 inches high by 23.5 inches wide by 13.5 inches deep at 125 pounds.
