    CMI Class B Strongroom Door & Frame G-CDB4 – Certified, Government-Approved Strongroom Security

    The CMI Class B Strongroom Door & Frame G-CDB4 is engineered to provide exceptional security for high-risk environments, including government facilities, financial institutions, secure storage vaults, and commercial strongrooms. Fully certified by the Security Construction and Equipment Committee (SCEC) for Class B protection, this strongroom door meets Australian government security standards, ensuring that your facility complies with official security requirements.

    Designed for maximum resistance to forced entry, manipulation, and drilling, this strongroom door is fitted with advanced security mechanisms, including a KABA X10 digital dial lock – a trusted, mechanical, battery-free locking system used in critical security applications.

    Why Choose the CMI G-CDB4 Strongroom Door & Frame?

    1. Certified Class B SCEC Approval

    The G-CDB4 strongroom door is officially SCEC Class B approved, ensuring it complies with the Australian Government’s strict physical security specifications for facilities requiring certified high-level access control. This makes it ideal for classified environments, defence applications, and high-security commercial storage.

    2. High-Security Locking System – KABA X10 Digital Dial Lock

    This door is equipped with the KABA X10 digital dial lock, a battery-free, fully mechanical lock used in secure government environments. Its advanced design resists manipulation, electronic attacks, and power failure, making it one of the most secure locking mechanisms available for strongrooms.

    3. Multi-Bolt Locking Mechanism with Glass-Triggered Deadlocks

    The CMI G-CDB4 features 11 x 32mm solid locking bolts along the sides and top of the door, offering robust resistance against prying or cutting attacks. Additionally, glass-activated deadlocking devices are installed to prevent unauthorized tampering – if the glass is broken during an attempted breach, the internal mechanism activates a deadlock, rendering the door completely immobile.

    4. Emergency Internal Release & Entry Monitoring

    For operational safety, the door is fitted with an emergency internal release mechanism, ensuring occupants can safely exit if accidentally locked in. It also comes with multiple microswitches, allowing the status of the door, lock, and entry points to be monitored via an alarm or security system – an essential feature in high-surveillance environments.

    5. Full Hardplate Protection & Fire Pan Included

    The 174mm overall door thickness includes a fire pan layer for added thermal protection, while hardplate shielding reinforces all vital locking components, providing drill resistance and extended attack delay.

    6. Flexible Installation & Custom Configuration

    The clear opening dimensions of 1980mm (height) by 860mm (width) offer a generous access point for secured environments. The clear masonry dimensions of 2060mm (H) x 1020mm (W) ensure compatibility with industry-standard construction. Customers may specify left-hand or right-hand swing, and wall thickness must be provided during ordering for precise fitment.

    Additionally, if required, the strongroom door can be packed in a timber crate for secure delivery, at an additional cost of $523 including GST.
