Underfloor safes

An underfloor safe is fitted beneath your floor, encased within reinforced concrete. It offers the combined benefits of almost complete concealment and immense strength. It is inconspicuous, space-saving, and unlike a traditional floor-standing safe, it cannot be simply lifted away by a burglar. An underfloor safe offers the highest possible security at a relatively low-cost. The only person who will know it’s there, is you…

Hamber Safes

Hamber Safes are an independent, family company. We have been making specialist underfloor safes for over 60 years, and are the original patent holders. All our safes are individually hand-built by our team of artisan engineers here in our Essex factory (they are not mass-produced on a production line). We use the very highest-quality materials available, without compromise. Our safes are purposely designed to be easy-to-install and simple to use. They are recommended by master locksmiths, security consultants and insurance experts, and are known as ‘the Rolls Royce of underfloor safes’. All our products are supported by a 5-year manufacturer’s warranty.

Model description

The ‘Dreadnought ABP’ is the ultimate underfloor safe with an unrivalled technical specification and no serious industry rival. In addition to an array of integrated standard features that are designed to resist all types of criminal attacks, it incorporates specialist ‘ABP’ protection to provide additional resistance to attack by flame cutting, along with specialist military-grade manganese steel anti-drill plates, and a ‘VdS Class 3’ lock (we are unaware of any other underfloor safe that has a lock of this high standard).

The Dreadnought ABP is suitable for the secure-storage of all types of valuables including cash, jewellery, watches, bullion, coins, cryptocurrency wallets, etc. Because of its peerless design and quality, it is the preferred choice of many individuals who have exceptional security needs, or who want to safely store items of very high importance or value.

The Dreadnought ABP consists of a robust, solid steel storage vault, and a connecting circular neck, that is fitted under your floor, encased in reinforced concrete. A fully-removeable, highly-engineered circular locking door is fitted into the opening on the top of the storage vault and this is packed with integrated features to resist all types of criminal attack (including drilling, abrasive cutting, flame cutting, lock tampering, heavy impact, leverage and wedging, and fire).

Like all Hamber underfloor safes, the Dreadnought ABP is designed for simple retrofitting in to existing homes, or can also be fitted during the construction phase of new homes. It is suitable for installation in any floor type, modern or period, concrete or wooden (and can even be fitted above the floor disguised as a window seat etc.). Full installation instructions are provided.

The Dreadnought ABP has a manufacturer’s minimum cash rating of £35,000 (£350,000 for jewellery and other valuables), equivalent to Eurograde 3 or above. We provide it with this rating as this is the highest cash rating normally attributed to an underfloor safe on the insurance industry ‘Safe List’. We do not believe however that the Dreadnought ABP is a conventional underfloor safe in any way, and its unrivalled specification and quality make it truly exceptional and worthy of a higher classification of its very own. Compare the list of features listed below with any other available alternative to satisfy yourself that the Dreadnought really is the ultimate underfloor safe.

Standard technical features

• Insurance recognised, ‘VdS’ Class 3, high-security lock (with 9 levers and double-bitted keys).
• Removeable locking safe door, machined from a solid, round, stainless steel blank (42mm thick before the addition of copper ‘ABP’ plates, manganese steel anti-drill plates and other components), giving an actual access opening of 142mm in diameter.
• Two over-sized, sliding, stainless steel locking bolts, 37mm by 12mm and fitted in a unique concealed V-groove arrangement.
• Solid stainless steel internal components and mechanism.
• High-tech ceramic materials fitted in crucial locations to resist drilling and to cause drills to slip and lose traction.
• Three integrated ‘relocking’ mechanisms fitted to resist lock and bolt work tampering (these put the safe into a ‘failed safe’ condition if attacked).
• Self-releasing door handle that is designed to detach if an attacker attempts to use it to pull the safe out of the ground with heavy-lifting equipment.
• Robust ABS lock cover fitted to the underside of the removeable door to completely enclose the lock and internal mechanisms and protect them from dust and detritus.
• Deluxe metal key escutcheon plate fitted that covers the keyhole and prevents the ingress of dust and detritus (the plate is stamped with the unique safe build number).
• Hand-welded storage vault with continuous-welds on all seams and collar, and fitted with a triple thickness (30mm) armoured top plate and an anti-extract flange (the vault is hard powder-coated to resist corrosion after installation in concrete, and has a luxurious flock-coated, soft interior to protect your valuables).
• A flush, floor-level dust cover is provided to discretely finish off your installation (and can be hidden under a decorative floor covering if preferred).

Special technical features

• Indirect locking bolt actuation: The Dreadnought ABP is fitted with a control knob (a slider on combination models), that operates the locking bolts completely independently of the operation of the lock. This enhances security, lessens the strain (and wear) on the lock, and allows a smooth locking bolt action.
• ‘ABP’ Protection: The Dreadnought is fitted with a specialist feature to provide additional resistance to attack by flame-cutting equipment (known as ‘Anti-Blow-Pipe’ in the industry). This includes two 4mm thick copper plates that cover the whole of the door surface. These act as a ‘heat sink’, attracting the intense heat from flame-cutting equipment and neutralising attempts to cut through.
• Manganese steel anti-drill plates: In addition to the above, two supplemental 4mm thick manganese steel anti-drill plates are also fitted that cover the whole of the door surface and provide further resistance to drill and abrasive cutting attacks. Specialist manganese steel plates to provide additional resistance to attacks by drilling or abrasive cutting (an exceptionally hard material used by the military in bullet proof equipment and to crush rocks in the mining industry. We are unaware of any other underfloor safe that incorporates this super-hard material.

Special design features

• Designed for genuine single-handed operation (an essential feature of an underfloor safe). Simply turn the key, twist the control knob, and lift the removeable access door out by the handle to remove it. Deposit your valuables inside the storage vault. Then, lower the door back into the opening, in any direction (360 degrees), twist the control knob, turn the key, and it’s locked again (there are no awkward brackets or lugs to locate).
• Fitted with a reassuring ‘key-retaining’ feature (again an essential feature of an underfloor safe). The key cannot be removed after the removeable safe door is lowered back in to the vault opening, unless the locking bolts are in place and the door is fully locked. If you can remove the key with the door placed in the safe opening, you can rest assured that your safe is locked.
• Unique ‘quick-key-change’ feature: If a single key is lost, mislaid or stolen, there is no need to fit a new lock to restore the complete security of your safe. Instead, as long as you still have one of the original keys, the original lock can be reset in minutes to use a new key set with a new pattern (disabling the original key pattern). Simply contact us to purchase a new pattern key set and we can guide you through the simple process (no lock dismantling is necessary).

Options

• Storage vault sizes: 27 and 34 litre capacity. Contact us for availability.
• Optional alternative locking options: The Dreadnought ABP can be built with standard key locking or alternatively with mechanical combination (dial) locking.
• ‘Quick-deposit-tube’ option: Allows valuables to be deposited ‘on-the-go’ through an additional small opening on the top plate (without the need to unlock the safe). Complete with drop capsules and an integrated anti-fish mechanism.
• Unique ‘detachable-bit’ key system available: Space-saving key option that allows the short, pattern-part of the keys (the ‘bit’), to be detached from the key stem, so they can be easily kept in a purse or wallet (rather than carrying a bulky complete key).
• Additional neck section: An additional neck can be purchased for the Dreadnought ABP and two neck sections can then be joined together to allow a double-thickness reinforced concrete encasement (this is only required for exceptionally high-security installations).
• Bespoke safe-building service: Often available if you have special or non-standard requirements. Contact us for full details.
