CMI Strongroom Commander Grade CRD4 – Built for Unmatched Strongroom Security
The CMI Strongroom Commander Grade CRD4 door is the pinnacle of strongroom protection, engineered to meet the most demanding security requirements for both commercial and high-value residential environments. Built to TDR (Torch and Drill Resistant) standards, this robust door provides superior resistance against a wide range of forced entry attempts, including explosives, hydraulic tools, pneumatic equipment, oxy-acetylene torches, and other industrial-grade cutting instruments.
At its core, the CRD4 strongroom door features a 100mm slab composed of a laminated alloy and refractory material, forming the heart of its 180mm total door thickness. This composition creates a formidable barrier that is nearly impenetrable under high-temperature and high-pressure attacks, making it the ideal solution for banks, armored vaults, data storage centers, and high-risk commercial sites.
Beyond physical resilience, the CMI Commander CRD4 includes glass-activated relocking devices as standard. These are triggered in the event of tampering or attack, immediately re-securing the locking mechanisms internally. This advanced feature significantly increases resistance to both drilling and thermal assaults.
Why Choose the CMI Strongroom Commander Grade CRD4 Door?
1. Ultimate Physical Protection
The CRD4 door provides multi-layered physical defense by combining alloy laminates and refractory materials within its massive slab core. This specialized combination is highly resistant to heat, force, and mechanical assault, making it an elite choice for facilities that require non-negotiable security standards.
2. Torch & Drill Resistant (TDR) Engineering
This strongroom door is purpose-built to resist attacks from tools commonly used in professional break-ins. From oxy-acetylene torches to pneumatic drills and hydraulic tools, the CRD4 ensures your assets are safe from even the most advanced intrusion methods.
3. Dual Independent Locking Mechanism
Security is further enhanced by a dual-locking system that allows locks to be used independently. You can choose from dial combination, key, or digital locking systems, depending on your operational needs. Each locking option functions as a stand-alone system, increasing access control and flexibility.
4. Glass Relockers for Anti-Tamper Defense
If tampering is detected, the glass relockers activate automatically, reinforcing the internal lock system to prevent any further breach attempts. This mechanism is especially effective in delaying or neutralizing drilling-based attacks, buying critical response time.
5. Emergency Internal Release
As standard, the CRD4 door includes an internal release mechanism, ensuring that anyone inside the strongroom can exit safely in emergencies, without compromising external security protocols.
6. Alarm System Integration
This door supports the integration of electronic and duress alarm systems, making it an excellent addition to smart security infrastructures where real-time threat alerts and monitoring are critical.
