Altronix MM4 Mounting Magnets Four-Pack
The Altronix MM4 is a four-pack of magnetic mounting solutions designed to secure Altronix enclosures and compatible equipment directly to ferrous metal surfaces without brackets, fasteners, or drilling. Each pack contains four individual magnets, allowing distributed load support across mounting points or multiple installations from a single purchase.
When to Use Mounting Magnets
Magnetic mounting eliminates the friction and time cost of traditional bracketing. Where permanent installation is impractical—temporary field deployments, mobile security applications, or facilities where drilling into structural members is forbidden—magnets enable rapid placement and repositioning without tools or hardware. This matters in warehouse automation, mobile surveillance vehicles, and lease spaces where you need to preserve walls and move equipment as facility layouts evolve.
The MM4 assumes your enclosure has ferrous (iron or steel) mounting points and your target surface is ferrous metal—painted steel walls, equipment racks, vehicle frames, or large metal conduit. If your mounting surface is non-ferrous (aluminum, stainless steel, composite), these magnets will not grip. If your enclosure is aluminum or plastic, you'll need to verify magnetic attachment points or consider bracket alternatives.
Key Features
- Four magnets per pack: Allows single purchase to support a four-point mounting configuration, or distribute across multiple smaller installations. More mounting points mean more even load distribution and better resistance to vibration and shifting.
- Tool-free installation: No wrench, drill, or fasteners required. Magnets adhere directly to ferrous surfaces in seconds. Matters in field situations where carrying mounting hardware and tools adds friction to rapid deployment.
- Ferrous surface compatibility: Works on painted steel, bare steel, and steel structures. Confirm your target surface is ferrous metal—a magnet test takes 10 seconds and prevents wasted trips.
- Rapid repositioning: Unlike bolted brackets, magnets allow enclosures to be lifted and relocated without hardware removal or potential damage to mounting surfaces. Critical for test deployments or facility reconfigurations.
- No permanent marks: Magnetic mounting leaves no holes, fastener impressions, or paint damage. Important in leased or shared spaces where facility damage costs money and landlord relations.
- Lifetime Limited Warranty: Altronix backs the MM4 under its standard limited lifetime coverage, meaning manufacturing defects are covered for the working life of the product.
Deployment Considerations
Magnetic grip strength depends on magnet surface contact and ferrous surface cleanliness. Rust, paint buildup, and surface irregularities reduce adhesion. Clean your mounting surface with a wire brush or cloth before placing magnets. Vibration and impact can shift magnetically mounted enclosures; if your application involves frequent vehicle movement or mechanical shock, consider bolted backup or additional magnets for redundancy.
The MM4 is not rated for horizontal (sideways) or hanging loads—use these for equipment that rests against a vertical ferrous surface (walls, panel mounts, equipment frames). Weight limits depend on magnet quality and surface contact area; Altronix specifications should be consulted for exact load ratings per magnet. Do not assume all four magnets can be used in a single point-load scenario without verification.
If your enclosure requires both magnetic mounting and electrical grounding, ensure ground continuity is maintained through your cabinet or separate grounding conductor—magnets alone do not provide electrical ground paths.
Integration & Compatibility
The MM4 is designed for Altronix enclosures and equipment with ferrous mounting surfaces. Verify that your specific Altronix model supports magnetic mounting before ordering. If you are mounting Altronix power supplies, distribution modules, or control enclosures to a ferrous surface and the enclosure includes magnetic mounting points, the MM4 will integrate directly without modification.
Frequently Asked Questions
Q: Will these magnets work on stainless steel or aluminum surfaces?
A: No. The MM4 magnets are designed for ferrous metals (iron and steel). Stainless steel and aluminum are non-ferrous and will not be gripped by these magnets. Test your surface with any magnet before purchasing.
Q: Can I use fewer than four magnets?
A: Yes. The four-pack allows flexibility—you can use two magnets for a smaller enclosure or distribute them across multiple installations. Confirm your enclosure weight and magnet load rating to ensure safe support.
Q: Are there weight limits per magnet?
A: Weight capacity depends on magnet design and surface contact quality. Consult the Altronix MM4 datasheet or contact the manufacturer for maximum rated load per magnet to ensure safe installation.
Q: Can these magnets be used for permanent outdoor installations?
A: Magnets themselves are passive and weather-resistant. However, your enclosure must be rated for outdoor exposure (IP rating, corrosion resistance). The magnets will not degrade outdoors, but they are best suited for semi-permanent or temporary deployments where repositioning may be required.
Q: Do these magnets provide electrical grounding?
A: No. Magnetic adhesion does not create electrical grounding. If your enclosure requires ground continuity, run a separate grounding conductor or verify ground integrity through your mounting structure.

The Altronix MM4 is a straightforward accessory that solves a real field problem: getting enclosures mounted on ferrous surfaces without power tools, anchors, or facility damage. In my experience, the friction cost of sourcing brackets, fasteners, and drilling in leased spaces is higher than most people account for. A four-pack like the MM4 is one of those things that sits in your van and saves half a day on a warehouse retrofit or mobile vehicle deployment.
Deployment Realities:
- Surface preparation matters more than magnet quality: A rusty or paint-heavy ferrous surface will cut magnetic grip by 30–50%. Five minutes with a wire brush on the target wall before installing the magnets is not optional—budget for it in your site survey.
- Load distribution across four mounting points is the intended design: Using all four magnets in a single-point load scenario defeats the purpose. Spread them across the footprint of your enclosure to minimize rocking and vibration shift. This is especially critical in mobile or vehicle-mounted applications.
- Vertical mounting is the sweet spot; horizontal or overhead is not recommended without structural verification: Gravity works in your favor on a wall-mounted vertical surface. If you are attempting to mount an enclosure sideways or inverted, do not assume the magnets alone will hold safely under vibration or impact.
Installation Shortcut: Keep a spare set of MM4 magnets in your field kit. Field enclosures sometimes need to be repositioned mid-project—temporary test locations, interference mitigation, or reconfigured facility layouts. Having magnets on hand lets you move equipment without a second trip to source hardware.
The MM4 is best deployed in semi-permanent or temporary field installations where rapid placement and repositioning outweigh the need for permanent bracketing—warehouse automation pilot projects, mobile surveillance vehicles, and lease-space deployments where landlord approval for drilling is impractical or denied.
