Magnetic Lock Installation in Citrus
Short answer: Magnetic locks suit glass doors, double doors, aluminum storefronts and doors where cutting a strike pocket isn't practical. They are a weaker fit where the door must stay locked during an outage, because a maglock lets go when power is lost. In that case we'd look at an electric strike or an electrified lockset instead.

A maglock has no latch to wear out, no bolt to jam and no keeper to align, which is much of the appeal. It is simply a strong electromagnet and a steel plate. That design suits server rooms, records rooms, stockrooms and offices in Citrus where a door has to stay shut against a hard pull but open instantly when someone needs to leave. The tradeoff is a dependence on power and a design that must put the exit first. This page explains how magnetic lock installation works, what we check on site, what the code expects and what usually changes the price.
What to know first in Citrus
Doors dictate the hardware. An outswing steel door with a solid header takes a standard header-mount lock easily. An inswing door usually needs a bracket kit so the magnet and plate meet squarely. Aluminum storefronts have narrow headers and thin extrusions, so the magnet may need a through-bolted backing plate or may be better as a concealed shear lock. Tempered glass can't be drilled once it has been made, so glass doors use clamp-style brackets that grip the glass without any holes. Double doors need either two magnets or a combined unit, plus a plan for the inactive leaf. Wood doors need through-bolts long enough to resist pulling out. We look at the door, the header and the swing during the survey and choose the mounting kit before you see a price, because it is often the largest piece of magnetic lock installation. If the header cannot carry a magnet, we say so and suggest another route.
What we can do on-site
- Header-mounted maglocks on outswing doors. On an outswing door with a sound header, the magnet mounts on the frame above the door and the armature plate mounts on the door face directly beneath. This is the cleanest magnetic lock installation: a straight bolt-up, short wiring and good alignment. We check the header for strength and anchor into solid material, not drywall.
- Aluminum storefront doors and shear locks. Aluminum storefront frames have narrow headers and thin walls. A surface-mounted magnet can need a backing plate inside the extrusion, while a concealed shear lock hides in the header and clamps the top of the door. Shear locks cost more and need the right header depth, but they leave a very clean look.
- Double doors and paired magnets. A pair of doors can use two single magnets, a double-door unit on a shared header, or a magnet on one leaf with flush bolts on the other. The best choice depends on which leaves open, how often, and what the code expects. We map that out during the survey.
- Fire alarm release and code review. A fire alarm release uses a relay from the panel to cut lock power when the alarm activates. We install the relay on the lock's power line and test it with your fire alarm contractor, who has to trigger the panel. When building rules require sprinkler release too, we plan for that.
- Readers, keypads and controllers. A reader or keypad tells the controller to release the lock for a few seconds. We connect the reader, controller and lock, set the release time, and configure schedules and credentials. Cards or codes can be canceled instantly, which is far easier than rekeying a door.
What's different about Citrus
School offices, childcare centers, churches and youth-sports buildings in Citrus often use maglocks on glass entry doors so staff can control who comes in. Children and visitors must always be able to leave, which makes the sensor, button and fire alarm release central. We design for substitute staff and volunteers, label the exit button plainly, and keep the system simple enough for anyone to understand.
Inland heat stresses power supplies, batteries and plastic parts. A supply in an unvented ceiling can run hot and fail, and backup batteries age faster. Glass and aluminum doors expand in afternoon sun, which can shift plate alignment slightly through the day. We mount supplies where air moves, check alignment hot as well as cool, and put a battery replacement date on the label.
Common situations
- Picture a records room in a clinic. Only certain staff should enter, and the door is rarely used but must be monitored. We'd install a maglock with a bond sensor and a door-position switch, a reader outside and an exit sensor inside, plus an entry log, so the office manager can tell when the door was opened and whether it was left unsecured.
- A coworking space in a converted storefront wants evening card access on its double entry doors, while the landlord insists on no visible damage. We'd choose surface magnets with brackets mounted to existing holes where possible, hide cable behind trim, keep the work reversible, and give the landlord a simple drawing of what changed so the lease terms stay intact.
- A typical call: a small company keeps its network equipment in a closet with a hollow-metal door and a keyed knob that everyone has copied. The manager wants a keypad. We'd mount an inswing bracket kit, run cable above the ceiling, set a short release time, and discuss whether a strike on the existing latch might be a better fit.
- Suppose a heavy glass door slowly sags on its pivots, so the plate no longer meets the magnet squarely and the door pulls open with a firm tug. The lock isn't weak; the door has moved. We'd adjust or replace the hardware that holds the door, realign the plate, and confirm full contact before blaming the magnet.
How the visit works
- Survey the door, header and exit path. We look at the door type, how it swings, the header and frame, the glass, the closer and the hinges. Then we trace how a person leaves: where they stand, what they reach for and what could stop them. The exit comes first because everything else depends on it.
- Design the release path and quote. A good design starts with the exit. We list every way the door releases, then add the credential that lets people in. You see the quote door by door, with notes on what could change. Nothing is drilled until you have approved it.
- Mount the magnet and armature plate. We mark the layout, drill and anchor the bracket or backing plate into solid material, and mount the magnet square to the door. The plate goes on the door with through-bolts and a flexible bushing so it can seat flat against the magnet face, and we tighten everything to specification.
- Run the power, sensors and fire alarm release. The push button interrupts lock power directly, the sensor does the same through its relay, and the fire alarm relay does it for the building. We test each one independently by operating it with the others disconnected.
- Program credentials and set the timers. We set the door-held-open alarm, the lock's release delay and the sensor's hold time so they work together. Then we check that a credential, a button press and a sensor trigger each behave properly when tried separately and in sequence.
- Test every release and hand over. Handover includes a short checklist: monthly button test, periodic cleaning of the plate and magnet face, and battery replacement every few years. We write the lock model, voltage and holding force on a label inside the enclosure, so future service doesn't start with guesses.
How we quote the job
- Exit devices and fire alarm interface. Fire alarm interface varies. Some buildings have a simple relay available; others require the alarm contractor to do the work or sign off. We tell you which situation you are in during the survey, so the schedule and budget account for it.
- Power supply, backup and controller. Maglocks draw power continuously, so the supply is a real component. A fused, regulated supply costs more than a plug-in adapter and does the job properly. Battery backup, a controller and readers add more. We build the list so you can add or skip items.
- Permits, inspections and timing. Scheduling flexibility helps. Work done in one planned visit during normal hours is simpler than a rushed one. We start at 6:30 a.m. every day, so many installs can be finished before a business opens. Tell us about inspection dates, tenant move-ins and opening days early, because our proposed schedule works backward from those.

Practical tips before you call
- Keep the magnet and plate faces clean. Wipe them with a dry cloth. Paint, tape, stickers and grease all widen the gap and reduce holding force. Never paint the faces, and don't cover them with decorative trim. A magnet that seems to have lost its grip is often just dirty or misaligned, so check those first.
- Don't plan a maglock for a door that must stay latched in a fire. Rated doors, stair enclosures and some corridors have specific rules. Ask your fire marshal or building department before you buy hardware, and tell your installer what the door is and where it leads.
- Review who holds access a few times a year. Cards and codes pile up as staff, vendors and contractors come and go, and every extra credential is a door that opens for someone. Remove what you no longer need and keep a short list of current holders.
- Think about off-hours security. A maglock lets go when power fails, so a blackout can leave a door unlocked. If that matters overnight, consider battery backup, a separate keyed lock where exit rules allow it, or an electric strike. Each has tradeoffs, and we will walk through them.
Common errors that cost time and money
- Skipping the alignment check. A plate that sits at an angle, or a gap wider than a business card, delivers only a fraction of the rated holding force. Tighten the plate with the door closed, then confirm the faces meet fully.
- Using a maglock where the door must stay latched. Fire-rated doors, some stairwells and other openings need hardware that latches positively, which a maglock does not do. Ask your building department before you specify one. If you are not sure how your door is classified, look for a label on the edge of the door or frame.
- Wiring the exit button through the controller only. If the controller hangs or loses power to its logic, the button does nothing. The push button should interrupt lock power directly, so the door opens even if the access system is dead.

Frequently asked questions
How strong is a magnetic lock?
Single-door models are commonly rated around 600 pounds of holding force, and heavier-duty units reach 1,200 pounds or more. The rating assumes the plate sits flat against the magnet, so alignment matters. The door, hinges and frame also limit what the lock can resist, which is why we look at the whole opening instead of the number on the box.
How long does magnetic lock installation take?
A single door with easy cable access is often a same-visit job. Glass doors, double doors, long cable runs, fire alarm coordination and inspections take longer. We give you a realistic schedule with the quote and plan around your hours so the door isn't left unsecured. Our day starts at 6:30 a.m. every day.
Can a magnetic lock work on double doors?
Yes. Double doors use either two magnets, one on each leaf, or a combined unit for pairs, with a plan for the inactive leaf. Both locks release together on one circuit, and the exit sensor and button must cover whichever leaf people will use to leave. We map that out during the survey.
Does a magnetic lock connect to the fire alarm?
Where a fire alarm system exists, the maglock normally drops out when it sounds, using a relay in the lock's power line. Some buildings add sprinkler or smoke detector release. The panel connection may need a licensed fire alarm contractor, and the release should be tested with them. We coordinate so testing doesn't surprise your alarm monitor.
Can you put a maglock on a glass door?
Yes. Tempered glass can't be drilled, so we use glass-door brackets that clamp the armature plate to the glass without holes, and we mount the magnet on a header, sidelight or mounting plate. We check the glass thickness, the pivot or hinge condition and the closer first, because a door that sags won't seat against the magnet.
Why does my door seem to stick after the magnet turns off?
That is residual magnetism, often caused by a worn or rusted armature plate, an over-tightened plate, or a plate with no flexible mounting. Cleaning the faces, loosening or replacing the plate and checking alignment usually cures it. It can also point to a failing lock or voltage problems, so we test the magnet before replacing parts.
How far is Citrus from your base?
