Hollon B3500: The Ultimate Security Solution for Valuables

The Hollon B3500 represents the pinnacle of in-floor safe technology, combining unbeatable security features with the stealth and durability required for both residential and commercial environments. As a B-rated safe, it is designed for foundation installation, offering unparalleled protection and concealment for a wide array of valuables, including gold coins, jewelry, paperwork, and more.

Robust Construction for Maximum Protection

The construction of the B3500 is second to none, with a 1/2” thick solid steel door that sets a formidable barrier against unauthorized access. This is further reinforced by five chrome-plated solid steel locking bolts, ensuring that once the safe is locked, it remains impervious to common burglary methods. The safe’s dimensions (18″ x 13.50″ x 23.50″ outside and 16.50″ x 13″ x 23″ inside) and weight of 115 lbs make it a substantial security fixture that can accommodate a significant volume of valuables while remaining discreetly hidden within a property’s foundation.

Advanced Security Features

At the heart of the B3500’s defense mechanism is the U.L. listed Group II lock, renowned for its reliability and resistance to tampering. This high-security lock is complemented by a spring-loaded re-locking device and a full-length dead bar, providing an additional layer of security in the event of lock tampering or removal attempts. The inclusion of a drill-resistant hardplate protects the lock from drilling attempts, ensuring that the safe’s contents are secure against one of the most common breach methods.

Ease of Use and Durability

Despite its robust security features, the B3500 is designed with user convenience in mind. An air-spring bar enables the door to be opened easily, allowing for hassle-free access to the safe’s contents. The powder-coated finish offers more durable protection against wear and corrosion, ensuring that the safe maintains its integrity and appearance over time.

Concealment and Installation

One of the B3500’s most significant advantages is its potential for concealment. Once installed in concrete and covered with a rug or carpet, the safe becomes nearly impossible to detect, offering an added layer of security through obscurity. Even if detected, the safe’s integration into a building’s foundation means that removing it would require significant effort and tools, as ordinary drills or tools available at a hardware store cannot compromise its hardened steel door or structure.

Ideal for a Range of Applications

Whether for securing high-value items in a residential setting or safeguarding cash and sensitive documents in a commercial environment, the B3500 is versatile enough to meet diverse security needs. Its affordability, coupled with the high level of protection it offers, makes it a favored choice among those looking for reliable safes for sale that can be used in various settings without compromising on security or quality.

Choosing a Hollon B3500 floor safe means investing in a product from a brand that’s synonymous with quality and reliability.

With Hollon, customers are assured of a high-security safe that offers decades of problem-free usage, backed by the trust and expertise of a leader in the security industry.

Enhanced Security Measures for Uncompromising Protection

The Hollon B3500 isn’t just built to deter casual tampering; it’s engineered to withstand sophisticated burglary attempts. The heart of its security lies in the 1/2″ thick solid steel door, designed to resist attempts at forced entry. This is complemented by five chrome-plated solid steel locking bolts, which, when engaged, provide an impenetrable barrier to unauthorized access. These features ensure that whether for personal or commercial use, the B3500 offers a level of security that is hard to bypass.

Drill Resistance for Added Peace of Mind

One of the B3500’s standout features is its drill-resistant hardplate. This component is crucial in protecting the lock mechanism from drill attacks, a common method employed by burglars to compromise safes. The hardplate is constructed from hardened steel, capable of defeating even the most persistent drilling attempts. This level of protection is indicative of Hollon’s commitment to providing safes that offer more than just a deterrent; they provide near-absolute security against a wide range of burglary tools and techniques.

Concealment and Installation: A Stealthy Approach to Security

The true genius of the B3500 lies in its ability to blend into the very fabric of a building. Installed in concrete and hidden beneath a floor covering, the safe offers unparalleled concealment. This not only makes it difficult for burglars to find but also significantly enhances the safe’s security by integrating it into the building’s structure. The process of discovering and attempting to remove the B3500 would require considerable effort and noise, further deterring potential theft.

Ease of Access and Durability

Despite its robust security features, the B3500 remains user-friendly. The air-spring bar facilitates easy opening of the door, a feature that enhances access without compromising security. Moreover, the powder-coated finish ensures the safe’s durability, protecting it against corrosion and wear from environmental exposure. This balance of accessibility and long-term protection makes the B3500 a wise choice for anyone looking to secure their valuables without constant maintenance worries.

Unmatched Security and Durability

With its 1/2” thick solid steel door, spring-loaded re-locking device, and full-length dead bar, the B3500 offers exceptional resistance against forced entry and sophisticated burglary attempts. The addition of 5 chrome-plated solid steel locking bolts and a drill-resistant hardplate ensures that the contents remain secure under all circumstances. The safe’s durability is further enhanced by a powder-coated finish, providing long-lasting protection against corrosion and wear.

Seamless Integration and Concealment

One of the B3500’s most compelling features is its ability to blend seamlessly with its surroundings. Once installed in concrete and covered, it becomes virtually undetectable, offering not just physical security but also the strategic advantage of being hidden from view. This level of concealment, combined with the safe’s substantial weight and dimensions, ensures it remains anchored, providing a permanent and secure storage solution.
