Backed by a 5-year warranty on the body and 2 years on the lock, this safe offers long-term peace of mind for personal and commercial use.
Why Choose the CMI MiniGuard MG3 K Safe?
Whether you’re a homeowner protecting personal assets or a small business securing daily takings, the CMI MiniGuard MG3 K provides reliable, no-fuss protection that you can trust.
1. Built with Solid Australian Steel for Real-World Protection
Security starts with material strength—and the CMI MiniGuard MG3 K delivers where it counts:
-
The door is constructed from 8mm solid steel plate, offering strong resistance to prying, drilling, and cutting tools.
-
The body is made from 4mm steel plate, making it both durable and light enough for versatile placement.
This safe isn’t just a deterrent; it’s a physical barrier that slows down intruders and protects what matters most.
2. Heavy-Duty Locking Bolt System with Keyed Access
Fitted with a 25mm diameter bolt work mechanism, the MiniGuard MG3 K employs thick locking bolts to firmly secure the door into the safe body. This robust bolt system resists tampering and physical force, giving you reliable protection 24/7.
The safe is fitted with a high-quality key lock, ensuring simple access without the need for batteries or digital codes. For environments where fast, direct access is preferred—like retail counters or back offices—the key lock provides quick and consistent entry without digital failure risk.
3. Smart Internal Layout with Anchor-Ready Installation
Despite its compact profile, the CMI MiniGuard MG3 K Safe is surprisingly versatile inside:
-
It comes equipped with 1 adjustable shelf, so you can customize your space to fit different-sized items such as documents, cash boxes, USB drives, jewelry, and more.
For secure mounting, the base of the safe includes 4 x 12mm bolt holes, allowing it to be anchored firmly to the floor—a crucial feature to prevent theft by removal. Once bolted down, this safe becomes incredibly difficult for thieves to lift or relocate.
4. Ideal for Homeowners, Small Businesses, and Professionals
The MiniGuard MG3 K Safe is compact enough to fit into wardrobes, under desks, or inside cupboards—yet powerful enough to deter break-ins. It’s the perfect security upgrade for:
-
Homeowners storing passports, savings, or sentimental items
-
Small businesses managing petty cash, receipts, or sensitive records
-
Professionals such as lawyers, doctors, or consultants safeguarding private files
Its clean, professional appearance blends well with any setting while delivering the physical security that matters.
5. Trusted Warranty and Built-In Durability
One of the strongest selling points of the CMI MiniGuard MG3 K is the industry-leading warranty:
-
5 years on the safe body – a clear signal of CMI’s confidence in the materials and craftsmanship
-
2 years on the key lock mechanism, offering full coverage against functional defects
This level of after-sales support is rare for safes in this price and size category, making the MiniGuard MG3 K Safe an even more attractive investment.
6. Installation-Friendly Dimensions
Please note: the depth of the safe excludes handle and hinge projections unless specified. This makes planning for cabinetry or recessed installation much easier and ensures an accurate fit in tighter spaces
