You've reiterated your interest in the Coffre-fort Premium boîte WELKO US680 clé (WELKO US680 Key Lock Premium Safe Box). This confirms you're looking for a substantial, fire-resistant safe with a traditional, reliable key-lock mechanism.
Let's provide the detailed information for this specific model once more, ensuring all key aspects are covered, as it's a popular and robust choice for those preferring mechanical security.
Coffre-fort Premium WELKO US680 clé (WELKO US680 Key Lock Only Premium Safe Box)
Purpose: This specific variant of the WELKO US680 is designed for individuals or businesses that require a large-capacity, robust, fire-resistant safe, and specifically prefer the absolute reliability and traditional security of a physical key lock over electronic systems. It's perfectly suitable for substantial document storage, valuable collections, significant cash reserves, or even firearms (where regulations allow and space is sufficient) in homes, offices, or commercial settings.
Characteristics: It represents a significant step up in size and weight from models like the US620, providing considerable internal volume. Its key-lock operation means it's impervious to battery failure or electronic glitches, relying purely on mechanical integrity and the safe's robust construction.
Key Features (based on typical specifications for this model in Vietnam):
External Dimensions (H x W x D): H 680 x W 580 x D 500 mm. This provides a very substantial footprint and impressive external volume, allowing for a good amount of storage without being overly bulky.
Internal Dimensions (H x W x D): Internal space is maximized within its robust walls, typically around H 580 x W 450 x D 380 mm (this is a common internal dimension for safes of this external size after accounting for wall thickness and fireproofing). This offers ample space for standard A4 documents, folders, laptops, and various other valuables.
Weight: Approximately 300 - 450 kg. For a "Premium" and fire-resistant (implied by its series, even if "FE" isn't in the specific name for the key lock) safe of this size, a weight of around 350 kg ± 10 kg is a reliable expectation. This substantial weight significantly deters casual theft and provides a strong anchor.
Locking Mechanism: High-security physical key lock(s). This is the defining characteristic. Access is granted solely by using the correct mechanical key(s). WELKO often employs high-quality, complex, double-bitted or dimple keys that offer enhanced pick resistance compared to standard flat keys. This model will not feature a digital keypad, fingerprint scanner, or integrated electronic alarm system.
Fire Resistance: As part of the "Premium WELKO US..." series (which often includes fire-resistant properties), even the key-lock-only variants of these robust models are designed to offer strong fire protection. It is generally expected to be rated for 1000 - 1200°C for 2 hours, providing excellent protection for paper documents, digital media, and other heat-sensitive items from intense fire events.
Burglary Resistance & Construction:
Multi-layered Steel Construction: Built with inner and outer steel shells, filled with a thick core of dense, proprietary fire-resistant and anti-penetration composite material (e.g., concrete foam or specialized mineral compounds).
Robust Locking Bolts: Features multiple (typically 5-8+), large-diameter, solid steel locking bolts that engage deep into the safe's reinforced frame from the side of the door. These bolts provide strong resistance against prying and cutting.
Anti-Pry Design: The door and frame are precisely engineered to minimize gaps and resist prying attempts.
Heavy-Duty Hinges: Internal or external heavy-gauge steel hinges designed for durability and to resist forced entry.
Internal Configuration: Typically includes one or more sturdy, adjustable shelves, allowing for customized organization of items. It may also feature a small, internal lockable drawer for securing particularly sensitive smaller items.
Durable Finish: Coated with a high-quality, aesthetic, and durable paint finish (often scratch-resistant and anti-corrosion, like a "sơn vân búa" or hammer-tone finish) that ensures the safe maintains its premium appearance over time.
Anchoring: Equipped with pre-drilled holes at the bottom or back, allowing the safe to be securely bolted to the floor or wall. While its weight is a significant deterrent, anchoring provides an additional layer of security against unauthorized removal or tilting.
Advantages of Key Lock:
Mechanical Reliability: No reliance on batteries, electrical power, or electronic circuits, eliminating concerns about power outages or component failures.
Simplicity: Straightforward to operate, requiring only the physical key.
Cost-Effective: Often slightly more affordable than electronically or biometrically locked equivalents.
Traditional Security: Preferred by individuals who trust robust mechanical systems.
Disadvantages of Key Lock:
Key Management: The most critical aspect is the secure management of the physical key(s). Loss, theft, or unauthorized duplication of keys can compromise security. Losing the key typically necessitates a locksmith.
Less Convenient for Multiple Users: Requires physical key transfer or multiple keys for shared access, which can be cumbersome.
No Audit Trail: Does not record access times or who has opened the safe.
No Integrated Alarms: Lacks the built-in electronic alarm features (for impacts, incorrect codes, etc.) found in digital models.
Availability & Price in Vietnam: The WELKO US680 with a key lock is a standard and popular premium safe available through authorized WELKO distributors and major safe retailers across Vietnam. Its price reflects its significant size, weight, and robust fire/theft protection.
