Supplier's note

  1. Technical Breakthroughs:

    • Dual Operation: Combine keyed and combination access for multi-user flexibility.
    • Zinc Alloy Body: 30% lighter than steel but maintains durability, reducing installation weight without compromising strength.
    • Anti-Tamper Cover: Conceals the keyway, deterring unauthorized access attempts.

  2. Version Selection Guide:

    • Base Model: Ideal for residential safes or low-traffic storage. Its standard security meets basic needs at an affordable cost.
    • Advanced Model: Suitable for commercial use (e.g., jewelry stores) with enhanced tamper resistance and expanded key capacity.
    • Pro Model: Designed for high-security environments (banks, data centers) with military-grade features and RFID integration for advanced access control.

With the Pro’s IPX6 corrosion resistance, you can install it outdoors or in humid areas without performance loss. Pair its RFID capability with the anti-tamper cover to create a virtually impenetrable security system.
