Secure precious metals, cash reserves, and vital documents with the Hayman PolyVault S-1200B-C Combination In-Floor Safe. Designed to be encased directly in concrete, this heavy-duty in-floor vault features a rustproof, seamless polyethylene outer shell paired with a drill-resistant 1/2-inch solid steel door and a UL Listed mechanical combination dial lock—delivering completely concealed, corrosion-free protection that burglars and fires cannot touch.
Key Features & Performance Highlights
- Rustproof Polyethylene Body: Constructed with a seamless molded poly body that eliminates ground moisture rust, seam leaks, and interior condensation common in traditional steel floor safes.
- UL Listed Combination Dial Lock: High-precision mechanical 3-wheel combination dial lock ensures reliable, battery-free access that never fails during long-term storage.
- 1/2-Inch Solid Steel "B" Rated Door: Heavy-duty solid steel plate door resists prying, impact, and mechanical leverage attacks when recessed into subfloor concrete.
- Hardplate & Internal Re-Locker Protection: A hardened drill-resistant steel plate shields the lock body, supported by a spring-loaded internal re-locker that deadlocks the mechanism if a drill attack occurs.
- Concealed In-Floor Design: Sits flush when installed into concrete slab foundations, allowing the vault to be easily hidden beneath rugs, carpets, or floating floors for complete stealth.
- Lift-Out Door Mechanism: Removable door lifts out entirely once unlocked, offering full, top-down access to the generous internal storage chamber.
- Thermal Protection via Concrete Encasement: Poured concrete surrounding the poly shell provides natural insulation, protecting paper documents and cash from extreme heat and structural collapse.

Frequently Asked Questions
What makes the Hayman PolyVault S-1200B-C different from standard metal floor safes?
Traditional metal in-floor safes tend to rust over time due to concrete curing reactions and ground moisture. The Hayman PolyVault uses a patented, seamless polyethylene outer shell that is completely rustproof and watertight, ensuring your cash and gold remain dry and protected.
How is the Hayman S-1200B-C installed into a concrete floor?
The safe is lowered into an excavated cavity in your concrete slab foundation and encased with fresh poured concrete. Once fully set, the door sits flush with the floor surface, allowing it to be concealed under carpets, rugs, or furniture.
Does the combination lock require batteries or power?
No. The S-1200B-C utilizes a completely mechanical UL Listed 3-wheel combination dial lock that operates reliably without batteries, wiring, or electronic components.
Are in-floor safes fireproof?
Yes, inherently. While in-floor safes rarely carry traditional factory fire ratings, embedding the safe body in solid concrete provides exceptional thermal insulation that protects internal contents from extreme fires and building collapses.
What are the interior dimensions and capacity of the S-1200B-C?
The S-1200B-C has interior dimensions of 13 3/4" x 12 1/2" x 12 1/2", giving 1.24 cubic feet (2,148 cubic inches) of storage capacity for cash, precious metals, and important documents.
What does the UL Listed rating on the S-1200B-C's combination lock mean?
The S-1200B-C's 3-wheel mechanical combination dial lock is UL Listed, meaning it has been independently tested and certified to recognized lock-construction and performance standards.
How does the S-1200B-C resist drilling attacks?
A hardened, drill-resistant steel hardplate shields the lock body, and a spring-loaded internal re-locker automatically deadlocks the mechanism if a drill attack is attempted.
How much does the S-1200B-C weigh?
The S-1200B-C weighs 78 lbs. Since it's designed to be lowered into an excavated cavity and encased in poured concrete rather than sit free-standing, the surrounding slab bears most of the load once installed.
What warranty protection comes with the S-1200B-C?
The S-1200B-C is backed by a 1-year parts and labor warranty plus a lifetime burglary guarantee.
How does the S-1200B-C's lift-out door mechanism work?
Once the combination dial is unlocked, the S-1200B-C's door lifts out completely, providing full, unobstructed top-down access to the storage chamber rather than a hinged swing-open door.
