Shanghai Kuntu Industrial Co., Ltd.’s “large safe with key” series is a heavy-duty security solution designed to store large volumes of valuables—such as multiple firearms, bulk cash, important business documents, or family heirlooms—while relying on the simplicity and reliability of key access. Unlike digital safes that depend on batteries or power, our large safe with key offers consistent, fail-safe access via high-security keys, making it ideal for users who prioritize traditional security or operate in areas with frequent power outages. Backed by over 20 years of manufacturing experience and BSCI-certified quality control, these safes are trusted by homeowners, gun collectors, small businesses, and financial institutions worldwide for their durability and unmatched security. The construction of our large safe with key prioritizes maximum protection and long-term durability. The body is crafted from 10–12 gauge cold-rolled steel (thicker than standard safes), with a reinforced door that features 6–8 anti-pry bolts (extending 18mm into the safe frame) to resist forced entry. The key lock uses a high-security brass cylinder with a unique pin tumbler configuration—preventing picking, bumping, or unauthorized key duplication. Each safe comes with two heavy-duty keys (made from hardened steel) that are engraved with a unique serial number, linked to the safe’s serial number for traceability. For added security, the key lock is hidden behind a removable steel panel—deterring potential intruders from locating and tampering with the lock. A notable application involves a gun collector in the United States who uses our extra-large safe (36”x24”x20”) to store 15+ rifles and handguns, along with ammunition and accessories. The collector praised the safe’s solid steel construction, noting that it withstood a break-in attempt (intruders tried to drill through the door but failed) and that the key access provided peace of mind—no risk of digital malfunctions or forgotten codes. The safe’s interior, which includes adjustable gun racks and a separate compartment for ammo, also helped the collector stay organized. For small businesses, such as convenience stores or jewelry shops, our large safe with key is a critical tool for securing daily cash deposits and high-value inventory. A jewelry store in Italy uses our large safe (30”x20”x18”) to store diamond jewelry overnight, with the store owner and manager each holding a key (requiring both to open the safe—adding a layer of accountability). The store owner noted that the safe’s fire-resistant rating (up to 60 minutes at 1400°F) was a key selling point, as it provides protection against accidental fires in the store’s wooden display cases. Our large safe with key series offers multiple size options to fit different needs: - Medium-large (24”x18”x16”): Ideal for homeowners with large jewelry collections or small businesses storing moderate cash volumes. - Large (30”x20”x18”): Suitable for gun collectors with 5–10 firearms or retail stores with high-value inventory. - Extra-large (36”x24”x20”): Designed for industrial use, gun enthusiasts with 10+ firearms, or financial institutions storing bulk cash. Our commitment to cross-cultural adaptability ensures our large safe with key meets regional needs. For example, in countries like Canada and Scandinavia, where cold temperatures can affect digital components, our key-only access is a preferred choice for rural homes and businesses. In the Middle East, where sand and dust are prevalent, we add a dust-sealed keyway to prevent debris from interfering with lock operation. Our foreign trade team also provides professional installation guidance—helping clients in countries like Brazil (with concrete floors) or Japan (with wooden floors) properly anchor the safe to prevent tipping or theft. Every large safe with key undergoes rigorous testing at our Shanghai factory, including: - Pry resistance tests: The door is subjected to hydraulic pressure to verify the anti-pry bolts hold. - Fire resistance tests: Safes are exposed to 1400°F for 30–60 minutes to protect documents and valuables. - Lock security tests: The key cylinder is tested with 20+ common picking tools to ensure resistance. We also offer customization options, such as adding interior lighting (for easy valuables retrieval), foam padding (to protect delicate items like jewelry or antique documents), or branded logos (for corporate clients like banks).
