HES AM3331 Maglock Mounting Brackets — Duro Heavy-Duty
The HES AM3331 is a set of heavy-duty mounting brackets engineered specifically for electromagnetic lock (maglock) systems in commercial and industrial access control deployments. Built with Duro construction, these brackets deliver the structural integrity and corrosion resistance required for permanent door and frame installations where system reliability directly impacts physical security.
Key Features
- Duro Construction: Heavy-duty material composition resists corrosion and wear in demanding indoor and outdoor environments — critical for installations subject to temperature swings, humidity, or salt spray that would degrade standard steel brackets.
- HES Maglock Compatibility: Engineered to mount both magnet and strike assemblies from the HES electromagnetic lock family, ensuring proper alignment and load distribution across the lock mechanism.
- Magnet and Strike Assembly Support: Accommodates both the electromagnet (mounted to the door frame) and the strike plate (mounted to the door), providing the dual-point mounting architecture that prevents frame flex and lock misalignment.
- Commercial and Industrial Rated: Designed for permanent installations in office buildings, warehouses, manufacturing facilities, and secure entry points where brackets must survive years of daily door cycles without degradation.
- Standard Door Frame Integration: Compatible with conventional wood and metal door frames, eliminating the need for custom fabrication or frame reinforcement in most installations.
- Complete Mounting Hardware Included: All fasteners, anchors, and installation templates are provided — reduces on-site sourcing delays and ensures consistent installation quality across multiple sites.
Integration and Compatibility
The AM3331 brackets integrate directly with HES electromagnetic lock systems, supporting both surface-mount and mortise lock configurations. When planning a door control retrofit, confirm your maglock model number against the HES compatibility matrix to ensure bracket alignment with your specific lock's mounting footprint. These brackets are not interchangeable with non-HES maglock brands — verify your lock vendor before ordering to avoid installation rework.
For larger multi-door deployments, reference the door control planning guide to coordinate bracket procurement with frame reinforcement, power distribution, and reader positioning. Duro brackets are suitable for both new construction (pre-frame installation) and retrofit scenarios (post-occupancy upgrades).
Typical Applications
- Secure entry doors in corporate office buildings and data centers
- High-traffic warehouse and logistics facility access control
- Manufacturing and production floor entry point lockdown
- Enterprise server rooms and sensitive equipment access gates
- Multi-door access control rollouts with standardized hardware
Deployment Considerations
Installation of the AM3331 requires proper door frame assessment — ensure the frame material (wood, steel, aluminum) can support the bracket load and maglock weight without flex. On weak or damaged frames, pre-install backing plates or structural reinforcement to prevent lock misalignment over time. The Duro material resists corrosion but does not eliminate the need for periodic inspection; in outdoor or high-humidity environments, schedule annual fastener checks to catch salt spray or moisture creep before locks become unreliable.
Frequently Asked Questions
Q: Are the AM3331 brackets suitable for outdoor doors?
A: The Duro construction provides corrosion resistance adequate for covered outdoor entries and areas with infrequent rain exposure. For fully exposed outdoor doors subject to constant rain or salt spray, confirm with your HES distributor whether additional weatherproofing or stainless-steel variants are recommended.
Q: Do the brackets fit all HES maglock models?
A: The AM3331 is engineered for HES electromagnetic lock systems. Verify your specific maglock model number against HES compatibility documentation before ordering — bracket mounting hole patterns and spacing vary by lock series.
Q: What fasteners are needed for installation?
A: All required fasteners and anchors for both frame and door mounting are included with the AM3331. Installation templates are also provided to ensure accurate hole placement and alignment.
Q: Can these brackets be installed on aluminum door frames?
A: Yes, the AM3331 brackets are compatible with aluminum, steel, and wood frames. Confirm the frame thickness meets the bracket's anchor requirements and that the frame has sufficient structural rigidity to support the maglock and bracket weight.
Q: What maintenance do the Duro brackets require?
A: Periodic inspection of fasteners and anchor points is recommended, especially in outdoor or high-humidity settings. The Duro material resists corrosion but does not eliminate the need for routine checks to ensure brackets remain securely mounted and locks remain aligned.
Q: How long do the AM3331 brackets typically last?
A: With proper installation and maintenance, Duro brackets deliver long-term performance in commercial environments. Lifespan depends on installation quality, door usage patterns, and environmental exposure — annual inspections help extend service life.

When you're designing a multi-door access control rollout, the bracket hardware is often an afterthought — but it's actually where lock reliability lives or dies. The HES AM3331 Duro brackets are built with that reality in mind: they're engineered specifically for HES maglock systems, not as a generic mounting solution. The Duro construction matters because it resists the corrosion and wear patterns that cause frame creep and lock misalignment over 3–5 years of daily use.
Technical Highlights:
- Duro Material Composition: Resists corrosion and environmental stress far better than standard steel brackets in humid or salt-exposure settings — reduces maintenance callouts and lock failures caused by fastener or bracket degradation.
- Dual-Point Mounting (Magnet + Strike): Properly distributes the electromagnetic holding force across both the door frame and the door itself, preventing the frame flex and lock misalignment that occur when only one side is rigidly mounted.
- Complete Hardware Kit: All fasteners, anchors, and installation templates are included — eliminates on-site sourcing delays and reduces the risk of using incompatible fasteners that could loosen over time.
Deployment Considerations:
- Verify frame material and thickness before installation — weak or damaged frames require backing plate reinforcement to prevent lock creep. The AM3331 brackets alone won't rescue a compromised frame.
- This is an HES-specific product. Confirm your maglock model number matches the HES compatibility matrix — don't assume brackets from one maglock vendor will work with another's lock.
- In outdoor or high-humidity environments, schedule annual fastener inspections to catch salt spray or moisture creep before it affects lock alignment or emergency egress.
The AM3331 is the right choice when you're deploying HES maglocks at scale across commercial or warehouse facilities where hardware standardization and corrosion resistance directly impact uptime. Skip these brackets if you're running non-HES maglock brands or if your environment is fully exposed to coastal salt spray — discuss stainless alternatives with your HES distributor in that case.
