8. Coffre-fort Premium WELKO US880 clé (WELKO US880 Key Lock Only Premium Safe Box)
Purpose: This is a very large and heavy-duty safe from WELKO's Premium line, specifically equipped with a traditional physical key lock. It's designed for users who require substantial storage capacity and top-tier fire and theft protection, but prefer the mechanical reliability and straightforwardness of a key-only system. It's suitable for major document archives, extensive valuable collections (e.g., jewelry, precious metals), large sums of cash, or other high-value assets in large homes, commercial businesses, or institutional settings.
Characteristics: The US880 is a significant step up in size and weight from the US680, offering considerably more internal volume. Its key-lock operation provides a dependable, traditional security solution without reliance on batteries or electronic components.
Key Features (based on available data for US880 models and general WELKO Premium characteristics):
External Dimensions (H x W x D): H 880 x W 600 x D 600 mm. This is a very substantial safe, providing an imposing presence and significant external volume.
Internal Dimensions (H x W x D): Internal space will be maximized, likely around H 700 x W 450 x D 450 mm (allowing for thick walls and fireproofing material). This offers very generous space for multiple stacks of A4 documents, large ledgers, bulk items, and more.
Weight: Approximately 600 - 850 kg. For a key-lock "Premium" and fire-resistant safe of this size (US880), a weight of around 650 kg ± 10 kg is a reliable estimate based on a blend of listings for the US880 models. This immense weight is a primary deterrent to any attempt at unauthorized removal.
Locking Mechanism: High-security physical key lock(s). This safe is opened solely by using the correct mechanical key(s). Given WELKO's premium positioning, these would be high-quality, often multi-point, double-bitted or dimple keys, designed to be highly pick-resistant. There are no electronic components (keypad, fingerprint reader, digital display) in this specific "clé" variant.
Fire Resistance: As part of the WELKO "Premium US..." series, which generally includes fire-resistant properties, this key-lock variant is expected to offer robust fire protection. It is typically rated for 1000 - 1200°C for 2 hours, providing excellent insulation and protection for paper documents, digital media, and other heat-sensitive items from extreme fire conditions.
Burglary Resistance & Construction:
Multi-layered, Heavy-Gauge Steel: Constructed with very thick inner and outer steel shells, with the cavity filled with a dense, proprietary fire-resistant and anti-penetration composite material (e.g., specialized concrete foam).
Numerous Heavy-Duty Locking Bolts: Features a significant number of large-diameter, solid steel locking bolts (typically 8-12+) that engage deep into the safe's reinforced frame from multiple sides of the door. These bolts are designed to resist cutting, drilling, and prying.
Anti-Pry Design: The door and frame are meticulously engineered for tight tolerances and anti-pry features, minimizing leverage points for attack.
Re-locking Device: While purely mechanical, some high-security key locks or the safe's bolt work itself might incorporate a mechanical re-locking device that will permanently secure the safe if the lock is attacked.
Internal Configuration: Will typically include multiple robust, adjustable shelves to allow for highly customizable internal storage. It may also feature a sturdy, internal lockable drawer for smaller, highly sensitive items, providing an additional layer of security.
Durable Finish: Features a high-quality, aesthetic, and durable paint finish (e.g., hammer-tone or smooth powder coat) that is resistant to corrosion and wear, ensuring the safe maintains its premium appearance.
Anchoring: Equipped with pre-drilled holes for securely bolting the safe to the floor. Given its extreme weight, anchoring further enhances its immovable nature, preventing unauthorized removal.
Advantages of Key Lock:
Unrivaled Mechanical Reliability: No dependence on batteries, power, or electronic circuits, making it immune to power outages or electronic malfunctions.
Simplicity and Directness: Straightforward operation; simply insert and turn the key.
Long-Term Durability: Mechanical locks are known for their longevity and can last for decades with minimal maintenance.
Cost-Effectiveness (relative to high-end digital/biometric): While a premium safe, the key-lock variant may be slightly more affordable than its electronic or biometric counterparts with similar features.
Disadvantages of Key Lock:
Key Management is Crucial: The primary vulnerability is the physical key(s). Loss, theft, or unauthorized duplication of the key(s) directly compromises security. Losing the key often necessitates a professional locksmith.
Less Convenient for Multiple Users: Requires physical key transfer for shared access.
No Audit Trail: Does not provide a record of who accessed the safe or when.
No Integrated Alarms: Lacks the electronic alarm features (for impacts, incorrect codes, etc.) common in digital models.
Availability & Price in Vietnam: The WELKO US880 with a key lock is available through authorized WELKO distributors and reputable safe retailers in Vietnam. Its price reflects its substantial size, immense weight, and top-tier fire/theft protection. As of May 2025, prices for the WELKO US880 clé would typically range from approximately 25,000,000 VND to 40,000,000 VND, depending on the specific retailer, any current promotions, and included services (such as specialized delivery due to its weight).
