Hayman FS4000 Polyethylene Floor Safe

B-Rate floor safe with rustproof polyethylene body, USA-built

For homeowners who want concealed in-floor storage that resists moisture, the Hayman FS4000 in the FS Series pairs a 1/2-inch solid steel door with a patented rustproof, leak-resistant polyethylene body. It carries a B-Rate burglary classification, ships with a UL-listed Group II dial combination lock, and is built in the USA for permanent slab installation.

Set into concrete beneath the floor, the FS4000 measures 20.25 inches high by 21.75 inches wide by 15.5 inches deep and weighs 88 pounds, yielding 2.64 cubic feet of interior space. The interior measures 17 inches high by 20.25 inches wide by 13.25 inches deep, with a clear door opening of 10.75 by 12.25 inches for documents, cash, and valuables.

Engineering & Security

• ✓1/2-inch solid steel door: The standard door earns the B-Rate burglary classification, with a factory upgrade to a 1-inch C-Rate door available.
• ✓Patented polyethylene body: Hayman's molded polymer body is rustproof and leak-resistant, suiting in-floor placement where moisture and corrosion threaten steel bodies.
• ✓UL-listed Group II dial lock: Combination dial comes standard, with an optional Securam digital lock upgrade for keypad entry.
• ✓Dual relock system: Backup relockers engage if the lock is attacked, helping hold the door secure during a forced entry attempt.
• ✓Drill-resistive hardplate: A hardplate shields the lock mechanism against drilling, a common method of attack on the locking package.
• ✓Not fire-rated by design: This is a burglary-focused floor safe; the FS Series carries no fire rating, so pair sensitive documents with a fire-rated box if needed.

Concealment & Installation

• ✓In-floor concrete mounting: Set the body into live concrete at floor level so the safe is anchored and hidden within the slab.
• ✓Flush steel cover plate: A steel cover plate sits flush with the finished concrete, letting the door blend into the floor surface.
• ✓Spring-assisted lift-off door: The patented spring-assisted door lifts off for easy access and is interchangeable across FS Series safes.
• ✓Anti-pry hinge bar: A solid steel bar on the hinge side resists prying, reinforcing the door against leverage attacks once installed.

Ideal Buyer & Use Cases

The Hayman FS4000 fits homeowners who want a concealed, corrosion-resistant in-floor safe for cash, documents, and valuables. At 20.25 inches high by 21.75 inches wide by 15.5 inches deep and 88 pounds with 2.64 cubic feet inside, it installs permanently into a concrete slab and disappears beneath flooring.

Buyers wanting a smaller steel-body in-floor option can consider the Hayman FS8 or FS2300B, while those needing more capacity can step up to the FS16, FS16D, or the larger FS16T. Body-only versions of several FS models are also available for retrofits.
