6 Best Weatherized Enclosures For Exterior Electromagnetic Locks

Installing electromagnetic locks on exterior openings requires more than just mounting hardware; it demands a robust barrier against the elements. Moisture, UV exposure, and temperature fluctuations will compromise standard indoor maglocks within a single season. Proper enclosures are the difference between a secure perimeter and a rusted, failing electronic system that invites liability. Choose wisely based on the specific exposure of the entry point to ensure long-term functionality.

Seco-Larm E-942F-1K3S/W: Best Overall Value

This enclosure hits the sweet spot between affordability and durability for standard storefront or warehouse exterior doors. It is designed specifically to protect standard maglocks from direct rain exposure without over-complicating the installation process.

The housing is constructed from stainless steel, which provides essential corrosion resistance in coastal or high-humidity climates. While it lacks the extreme armor of military-grade gear, it offers enough protection to stop water ingress from damaging the sensitive electronic coils inside.

Consider this model when working on budgets that don’t allow for custom-fabricated housing. It provides a clean, professional aesthetic that blends well with commercial door frames, provided the installer uses proper silicone sealing around the wire entry points.

SDC EHB Environmental Housing: Top Professional Pick

When a project demands the highest level of reliability for high-traffic entryways, the SDC EHB series is the industry standard. This housing is engineered to withstand harsh weather patterns, including wind-driven rain and snow, which often bypass cheaper covers.

The build quality here is superior, utilizing materials that minimize the thermal expansion issues often seen in cheaper plastic alternatives. Precision manufacturing ensures that the maglock aligns perfectly with the armature plate, reducing the risk of “buzzing” or misalignment common in inferior setups.

Contractors often prefer this unit for high-end office buildings where call-backs for lock failures are not an option. It features a heavy-duty design that integrates seamlessly with SDC systems, but remains versatile enough for most third-party maglocks.

RCI Weather Housing for IntelliMag: Best for Gates

Gates present a unique challenge because they are rarely under an overhang and often experience significant vibration. The RCI housing is built to accommodate these high-movement environments while shielding the internal components from direct exposure.

The geometry of this enclosure is specifically optimized for gate-post mounting. It provides a secure, rigid structure that keeps the maglock stable, even when a heavy gate slams shut repeatedly throughout the day.

Avoid using generic housings on gates, as the vibration will eventually compromise the integrity of the enclosure’s seals. This RCI unit manages stress forces better, which saves the hardware from loosening under heavy daily usage.

Dortronics 9100 Series: Most Vandal-Resistant

Vandalism is a genuine concern in urban construction projects, where exposed electronics are often targets for tampering. The Dortronics 9100 series provides a fortified barrier that discourages interference while maintaining weather resistance.

The heavy-gauge construction acts as an armor shell for the maglock, making it extremely difficult to pry or pry open without specialized tools. This is the preferred choice for alley entrances or parking garage access points where security is paramount.

While the material is tough, the installation must be precise to maintain its vandal-resistant properties. Ensure that the mounting screws are hidden or shielded once the unit is fully installed to prevent unauthorized removal of the cover.

BEA Universal Enclosure: Most Versatile Option

If a job involves an unusual door configuration or an older, non-standard maglock, the BEA Universal Enclosure offers the flexibility needed to get the job done. It is designed to fit a wide range of manufacturers, making it a reliable staple for any contractor’s service truck.

The enclosure features adjustable mounting slots that accommodate various hole patterns. This saves significant time on site, as the need for drilling new mounting holes in metal door frames is greatly reduced or eliminated.

It performs well in general exterior conditions, though it remains a “universal” solution rather than a specialized one. For highly corrosive environments like pool areas or near chemical plants, ensure the finish is compatible with the local atmospheric conditions.

Heavy-Duty Steel Box: Best for Custom Installs

Sometimes a pre-made enclosure won’t fit the architectural requirements of a custom job, such as a heavy timber gate or a glass-heavy storefront. In these cases, a heavy-duty, field-modified steel box is the professional’s go-to for a clean, structural fit.

Fabricating or modifying a steel enclosure allows for precise control over drainage and cable entry. Use a high-grade 316 stainless steel to ensure that the box doesn’t rust and leave streaks on the surrounding building facade.

Remember that custom-made boxes require careful attention to interior clearance. Always verify that the maglock has enough “float” to mate properly with the armature plate, otherwise, the door will not lock reliably.

What IP Ratings Mean for Your Exterior Maglock

An Ingress Protection (IP) rating is a two-digit code that tells you exactly how well the enclosure resists solids and liquids. For exterior use, look for an IP65 or higher rating to ensure the lock survives direct water spray.

• First Digit (0-6): Indicates protection against solids like dust or debris. A rating of 6 is dust-tight.
• Second Digit (0-9): Indicates protection against moisture. IP65 means it handles water jets; IP67 means it can handle temporary submersion.

Never rely on the manufacturer’s word alone when the project is in a hurricane-prone area. Always check the specific IP rating to ensure the enclosure matches the intensity of the environment.

Sealing Your Enclosure: A Pro’s Installation Guide

Even the best enclosure will fail if the wire entry points are left open to the elements. Use a high-quality, exterior-grade silicone sealant at every penetration point to create a watertight seal.

When running conduit into the enclosure, use liquid-tight fittings rather than standard connectors. These fittings feature rubber gaskets that expand when tightened, preventing moisture from wicking along the wiring inside the wall.

Always install a “drip loop” in the wiring before it enters the enclosure. A drip loop ensures that any water running down the cable is forced to drop off the bottom of the loop rather than traveling directly into the electronic housing.

Steel vs. Polycarbonate: Choosing the Right Case

Steel enclosures are superior in high-security, high-impact areas due to their inherent strength and longevity. However, steel is susceptible to rust if the coating is scratched, so ensure the finish is powder-coated or marine-grade.

Polycarbonate is an excellent alternative for areas where aesthetics and non-corrosive properties matter more than brute force. It will not rust, but it can become brittle over time when exposed to extreme UV rays in desert or high-altitude environments.

Select steel for high-traffic public access and polycarbonate for residential or low-impact commercial settings. If the site is near salt spray, go with stainless steel to avoid the accelerated corrosion that ruins standard metal boxes.

Maintaining Your Outdoor Lock for Long-Term Use

Outdoor maglocks require an annual inspection to ensure the enclosure remains sealed and the lock is functioning at peak efficiency. Use a mild soap solution to clean the surfaces and check the mounting hardware for signs of vibration-induced loosening.

Check the armature plate for any signs of oxidation, which can weaken the magnetic bond. A thin layer of light machine oil can prevent surface rust on the contact faces, provided the manufacturer’s guidelines allow for it.

Test the lock’s release mechanism under load to ensure that the enclosure isn’t creating friction against the door leaf. Regular maintenance keeps the entry system reliable and prevents the frustration of sudden electronic failure.

Selecting the right enclosure for an exterior electromagnetic lock requires balancing security, environmental exposure, and ease of installation. By prioritizing proper IP ratings and sealing techniques, you can ensure that the electronic access control system remains functional for years, regardless of the weather conditions. Avoid the temptation to cut corners, as the cost of a replacement or a building lockout far exceeds the initial investment in a quality, weatherized housing.
