Maglocks Versus Strikes for Commercial Doors

Maglocks Versus Strikes for Commercial Doors

A controlled opening is only as reliable as the hardware holding the door closed. When comparing maglocks versus strikes, the right answer is rarely about which product is stronger on paper. It comes down to the door, frame, existing lock hardware, life-safety requirements, how people leave the space, and what should happen during a power outage.

For offices, clinics, retail spaces, schools, and multi-tenant properties, both electromagnetic locks and electric strikes can work well with card readers, keypads, intercoms, request-to-exit devices, and access control systems. Their operating principles are very different, though. Selecting the wrong one can create unnecessary installation work, unreliable access, or an egress problem that must be corrected later.

Maglocks Versus Strikes: The Core Difference

A magnetic lock, commonly called a maglock, secures a door with an energized electromagnet mounted on the frame and an armature plate mounted on the door. When power is applied, the magnet holds the armature plate tightly against it. Remove power and the magnetic bond releases.

An electric strike is installed in the frame where the latch enters. Rather than holding the door with magnetism, it electrically controls the strike keeper so the latch can be released without turning a key or lever. The door remains mechanically secured by its existing latch, mortise lock, cylindrical lock, panic hardware, or exit device.

That difference shapes nearly every purchasing and installation decision. A maglock adds the locking force directly to the opening. An electric strike works with the door’s existing mechanical locking hardware.

When a Maglock Is the Better Fit

Maglocks are often chosen when the door does not have a practical latch arrangement for an electric strike, or when a surface-mounted installation is preferred. They are common on glass aluminum storefront doors, certain office doors, and openings where modifying a narrow frame pocket would be difficult.

Because a maglock has no latchbolt or keeper to align, it can tolerate some door and frame conditions that make electric strike installation challenging. The lock can be mounted at the header, with brackets available for various door and frame configurations. For double doors, paired maglocks may be used when both leaves need controlled access.

Maglocks also provide a direct holding-force rating, often expressed in pounds. That can be useful when specifying hardware for a large, frequently used door or a perimeter opening that needs substantial holding strength. The rating alone should not be treated as a complete security assessment, however. Frame strength, mounting method, door construction, and the rest of the access system all matter.

The major operational characteristic of a maglock is that it is generally fail safe. It requires power to stay locked. If power is removed, the door releases. This can be desirable where people must be able to exit during an emergency, but it means the opening is not secured during a power failure unless the system has backup power and the applicable code permits that arrangement.

Maglock egress requires careful planning

Maglocks require more attention to life-safety design than many buyers expect. Since the lock releases electrically, the egress path may need a request-to-exit sensor, a properly located emergency release device, fire alarm interface, and other components required by the authority having jurisdiction.

Requirements vary by occupancy, door location, local code adoption, and whether the opening is part of a required exit path. A maglock should never be selected simply because it looks easy to mount. The complete release sequence needs to be planned before hardware is ordered. For occupied commercial spaces, confirming requirements with the local authority having jurisdiction and qualified installer is the prudent approach.

When an Electric Strike Is the Better Fit

An electric strike is often the more natural choice for a conventional swinging door that already has dependable mechanical latching hardware. If a door has a cylindrical latch, mortise lock, or compatible panic device, the strike can provide access control while preserving familiar free egress from the inside.

For example, an office suite may use a card reader outside the door and a lever on the inside. When an authorized credential is presented, the electric strike releases the latch and the visitor opens the door. From the inside, turning the lever retracts the latch mechanically, without relying on an electronic release signal.

This arrangement is particularly useful on doors that must remain secure during a power loss. Many strikes are available in fail-secure configurations, meaning the strike stays locked when power is removed while allowing normal mechanical exit from inside. That makes them a common option for perimeter doors, employee entrances, and rooms where security continuity matters.

Electric strikes are also available as fail safe models, which release when power is lost. The correct function depends on the opening’s use, local code requirements, and the desired emergency behavior. “Fail safe” and “fail secure” are not quality grades. They are operating modes that must match the door’s purpose.

Strike compatibility is not automatic

An electric strike must match the lock hardware, frame preparation, latch type, and door alignment. A latch with a deadlatch function may require a strike designed to accommodate it. Rim exit devices, mortise locks, cylindrical latches, aluminum frames, hollow metal frames, and wood frames can each call for different strike styles and faceplates.

Door alignment also matters. A sagging door, binding latch, or damaged frame can put pressure on the keeper. If the latch is difficult to retract manually, an electric strike may not release consistently. Correcting the mechanical door condition before adding access control saves time and avoids service calls.

Installation and Maintenance Considerations

Maglocks are generally surface-mounted, but the wiring path, mounting brackets, armature plate alignment, and door movement must be handled correctly. The armature needs full contact with the magnet when the door closes. A warped door, misadjusted closer, or improper bracket selection can reduce holding performance.

Electric strikes usually involve more frame work. The installer may need to cut or modify the strike area, run low-voltage wiring through the frame, and fit the strike faceplate to the existing opening. On a fire-rated frame or door assembly, modifications must be evaluated carefully so the assembly’s rating and listing are not compromised.

Both products benefit from a stable power supply sized for the connected locks and access devices. Maglocks draw continuous power while locked, while most electric strikes draw power only during release, depending on the model and operating configuration. That difference can affect power-supply sizing, battery backup planning, and heat management in larger systems.

For maintenance, electric strikes depend on a clean, properly aligned latch and keeper. Maglocks depend on clean mating surfaces and secure mounting. Neither device compensates for a door that drags, slams unpredictably, or fails to latch consistently.

How to Choose for Your Opening

Start with the door instead of the access credential. Identify the frame material, door construction, handing, existing lockset or exit device, and whether the door is fire-rated. Then determine how people must exit, what happens during a power loss, and whether the opening is tied to a fire alarm or access control panel.

A maglock may make sense for a glass storefront door, a specialized frame, or an opening where surface-mounted hardware is the practical route and the egress system can be designed correctly. An electric strike may be the better choice for a standard commercial door with a good mechanical latch and a need for secure operation during a power outage.

Traffic level matters as well. High-use openings need hardware selected for frequent cycling, proper door closer adjustment, and reliable latch engagement. A light-duty strike on a busy employee entrance or an underspecified maglock on a heavy door can create avoidable failures.

Lockcetera’s commercial hardware selection is built around this application-first approach: choose proven hardware that fits the actual opening, not just the access control feature list. A few measurements, photos of the existing lock and frame, and a clear description of the desired power-loss behavior can prevent the most common ordering mistakes.

The best controlled door is one that users can operate naturally, managers can depend on, and occupants can always exit safely. Treat the lock as part of the complete opening, and the choice between a maglock and an electric strike becomes much clearer.
