CMI Strongroom Basic Grade BasicRD4 – Secure Access for Controlled Environments
The CMI Strongroom Basic Grade BasicRD4 is a cost-effective, entry-level strongroom door offering reliable physical security for environments where moderate protection is required. Built to AS/NZS 3809:1998 Basic Grade specifications, this strongroom solution is perfect for small businesses, commercial storage rooms, and low to medium-risk applications that demand strong access control without premium cost.
Constructed with an 80mm thick total door structure, this model features a 6mm solid steel front plate, supported by a mechanical relocking device. The relocker activates in the event of a forced attack, adding extra layers of resistance to deter intruders.
The boltwork system is engineered with 32mm thick high-grade steel bolts, providing two-way locking into reinforced lock chambers on both front and rear edges of the frame. These reinforced sections absorb force and impact, dramatically reducing the risk of breach during physical attacks.
Why Choose the CMI Strongroom Basic Grade BasicRD4?
1. Certified to AS/NZS 3809:1998 Basic Grade
This model meets the recognized Australian/New Zealand standard for basic-grade strongroom protection, making it an ideal solution for environments that require dependable physical security without excessive weight or cost.
2. Robust 80mm Door with Mechanical Relocking
The BasicRD4 door boasts a solid 6mm steel front section within an overall 80mm thick door. Internally, a mechanical relocking mechanism is built in to resist forceful tampering. If the lock is compromised during a break-in attempt, the relocker engages to keep the door securely shut.
3. High-Security Boltwork Design
A standout feature of this strongroom door is its heavy-duty bolt system. The 32mm diameter high-grade steel bolts secure both sides of the door simultaneously into reinforced lock chamber sections, ensuring comprehensive two-way locking and resilience under attack.
4. Reinforced Steel Frame & Threshold Plate
The door is mounted in a 4mm heavy-duty steel frame, complete with a 125 x 12mm threshold plate at the bottom for added structural strength and sealing. This configuration provides a solid, immovable frame-to-wall integration, enhancing the door’s resistance to prying or forceful removal.
5. Adjustable Hinges for Smooth, Reliable Operation
Durability and usability are enhanced through adjustable heavy-duty hinges with hardened pins mounted on pre-lubricated ball bearings. These ensure smooth door operation, even after years of daily use, and allow for hinge tension adjustments as needed.
6. Custom Configuration for Your Site
The CMI BasicRD4 is available in both left-hand and right-hand swing options, depending on your site’s access layout. Customers are required to specify wall thickness and hinge direction upon ordering to ensure a perfect fit and seamless installation.
