Strong Holding Force – Provides up to 510kg of magnetic holding force, ensuring secure door locking. Using brackets can reduce the holding force by up to 70%, so choose the right model of maglock for each door based on usage and security requirements.

Dual Voltage Compatibility – Operates on 12V or 24V DC, offering flexibility for different access control systems. If you’re retrofitting, ensure you select the correct voltage when on site.

Monitoring Facility – The 281-005 maglock has monitoring (hall effect) and a relay dry contact with LED. A monitored double maglock is also available in the Adams Rite 281-205 model. 

Low Maintenance – No moving parts mean minimal wear and tear, reducing maintenance time and costs. As part of your regular door hardware maintenance routine, still always include maglocks. Keep the armature plate and maglock surface clean so it is fully magnetised at all times.

Additional Security - This maglock features a security pin that prevents the unauthorised removal of the magnet once installed. It secures the maglock body to the door frame fixing plate.
