Defenders® are armoured door protections that defend cylinders against break-in attempts such as drilling, bumping, picking, cylinder extraction and acid attacks.
They are secured directly to the lock by means of special screws and holes, and are characteristically shaped to prevent break-in attempts by means of iron pipes. They are divided into different categories (mechanical, magnetic, electronic) and are available in numerous finishes to suit every type of door.
All Mottura Defenders® have been tested according to UNI EN 1906 and have passed the required tests to the maximum grade.

Mechanical Defenders® are the most popular type of armoured door protection. With steel spheres inserted at various points in the Defender's body, a protective manganese plate and other security mechanisms that vary for each model, they effectively protect the cylinder against break-in attempts using methods such as drill, pick and percussion blows. The use of the key is permitted through a small shaped hole.
Magnetic Defenders® add an additional level of protection for your security door lock compared to traditional mechanical models. A special cover completely seals the keyway and can only be rotated to show the keyhole using a special magnetic key. Only once the cover is fully rotated can the key be inserted to open the door.
The magnetic Defender® is the best form of protection against acid attacks, as well as against break-in attempts such as the use of a drill, pick, percussion blows and extraction of the cylinder rotor.
Electronic Defenders® add an extra layer of protection against major break-in attempts to your security door lock compared to traditional mechanical models. The keyway is protected by a manganese plate that completely seals the slot and is only released with a numerical activation code to be entered on the built-in keypad.
The electronic Defender® also allows personal activation codes to be provided for friends, family and trusted persons, unlike magnetic models, where a duplicate of the special magnetic key must be provided to each person. Service codes can be deleted at any time using the master code.
