This single door magnetic lock kit gives you a powerful 275kg (600lb) fail-safe maglock with everything needed to fit it to a single door – including a Z & L bracket for inward opening doors. It runs on 12V or 24V DC and works with exit buttons, keypads, fob readers, intercoms and fire alarm systems, making it a simple, reliable way to secure offices, shops, communal entrances and internal doors.
A magnetic lock has no moving parts to wear out or jam. When power is applied, the electromagnet holds the armature plate on the door with 275kg of force. When the power is cut – by an exit button, access controller or fire alarm – the single door magnetic lock releases instantly, so people can always get out.
Why choose this single door magnetic lock kit?
- 275kg (600lb) holding force: strong enough for most commercial and communal doors.
- Fail-safe operation: locks when powered and releases on power loss – the safe choice for exit routes.
- Dual voltage 12V / 24V DC: works with most access control power supplies.
- Z & L bracket included: lets you fit the maglock to inward opening doors.
- Complete kit: magnet, armature plate, bracket and fixings in one box.
- No moving parts: quiet, low maintenance and long lasting.
- Surface mounted: no need to cut into the door or frame.
Where can I use a single door magnetic lock?
- Office and reception doors with access control
- Shop, salon and clinic entrances
- Communal doors in flats and apartment blocks
- Internal doors to stock rooms, server rooms and staff areas
- Timber, aluminium and steel framed single doors
- Gates and doors used with intercom or door entry systems
How does a single door magnetic lock work?
The magnet is fixed to the door frame and the armature plate to the door. When the door is closed and the maglock is powered, the two lock together. To open the door, your exit button, keypad, fob reader or intercom cuts the power for a set time and the door releases. Because it is fail-safe, the lock also releases if the power fails or the fire alarm is triggered, as long as it is wired through a suitable power supply with a fire alarm input. For guidance on fire safety and means of escape in buildings, see the UK government’s Approved Document B.
Which bracket do I need?
For outward opening doors (opening away from the maglock side), the magnet usually mounts directly under the frame head, with an L bracket if extra depth is needed. For inward opening doors, use the Z & L bracket supplied in this kit, which brings the armature plate into line with the magnet. Not sure?

What else do I need?
A complete maglock system usually needs a 12V or 24V DC power supply (ideally with a timer and fire alarm input), a way to open the door from the inside and a way to get in from the outside. For the inside, choose a green press to exit button or our touchless exit button. For key-operated control, add our momentary key switch.
Frequently asked questions
Is this single door magnetic lock fail-safe or fail-secure?
It is fail-safe. It holds the door when powered and releases when power is removed, which is the standard requirement for doors on escape routes.
Will it work on an inward opening door?
Yes. Use the Z & L bracket included in the kit.
Can I run it on 12V and 24V?
Yes. It is dual voltage and works on either 12V or 24V DC.
Is a 275kg single door magnetic lock strong enough?
For most single commercial doors, yes. A 275kg (600lb) maglock is the most popular size for offices, shops and communal entrances.
Do you sell a version for double doors?
Yes. Our double door magnetic lock kit secures a pair of doors with two magnets. You’ll find it in our access control range.
