CMI Strongroom PRD4 – Premier Certified Protection for High-Security Environments
The CMI Strongroom Premier Grade PRD4 is one of the most secure and robust strongroom doors available on the market, engineered to meet the highest global certification standards in both the USA (UL TRTL-30×60) and Europe (ABIS Grade 5). Designed to withstand sophisticated forced entry attempts, including attacks with oxy-acetylene torches and high-powered drills, this door offers uncompromising protection for banks, government institutions, jewelry stores, pharmaceutical vaults, and high-value storage facilities.
The PRD4’s 135mm thick door features a 55mm reinforced slab core, composed of a lamination of high-tensile alloys and refractory materials. This combination is specifically designed to resist thermal and mechanical attacks, offering exceptional resistance to penetration, and making the PRD4 a trusted barrier between criminals and your most critical assets.
This strongroom door comes standard with a digital locking system, and can be customized with key lock, dial combination, or dual locking mechanisms upon request. Additionally, a glass-activated re-locker is installed by default, which triggers a deadlock in case of any tampering or breach attempts.
Why Choose the CMI Strongroom Premier Grade PRD4?
1. Dual International Certifications for Maximum Security
Certified by UL TRTL-30×60 in the USA and ABIS Grade 5 in the EU, the PRD4 meets some of the most stringent international testing standards for torch and drill resistance. This ensures it is capable of protecting against the most advanced criminal techniques used in real-world burglary scenarios.
2. Premier Grade TDR Construction
The core of the PRD4 door contains a 55mm slab of alloy and refractory composite, giving it exceptional resistance to thermal lances, angle grinders, and high-torque drills. The total door thickness of 135mm ensures that every access attempt is met with intense resistance, buying time and protecting assets.
3. Flexible Locking Options to Suit Your Security Needs
While the PRD4 comes standard with a digital lock, it can be upgraded to key lock, dial lock, or even dual locking systems (digital + key or digital + dial) for added protection. Customers can specify their preferred configuration at checkout for tailored security.
4. Advanced Re-Locking Mechanism for Tamper Protection
The glass-activated deadlocking re-locker included in the PRD4 is triggered during tampering attempts. It activates a secondary lock system, making forced entry exponentially more difficult. This feature is vital for environments where breach attempts may involve skilled intruders.
5. Internal Emergency Release Mechanism
For added safety, the PRD4 includes a standard internal release mechanism, ensuring that personnel inside the strongroom can exit safely in the event of accidental lock-in or emergency.
6. Hinging & Alarm System Compatibility
Customers can choose between standard right-hand or optional left-hand door swing to suit their vault layout. The PRD4 is also alarm-system ready, allowing seamless integration with any electronic or duress alarm systems, enhancing overall security monitoring.
