Mottura Defender®

The first protective barrier against break-in attempts.

A name that stands for guarantee

Mottura Defender® are sophisticated armoured protection mechanisms that act as a first, fundamental barrier against the main burglary attempts against home doors.

They are made of strong and durable materials, a state-of-the-art technology that is constantly being updated as security challenges increase, and their very design is engineered to prevent the localised action of a specific external agent (drill, pliers, cutter, hose or iron pipe).

Our Defender® range is designed to adapt to all types of requirements, whether in terms of different door leaf thicknesses or lock types, or in terms of the level of security needed, to ensure the perfect solution for every access.

Choose the Defender® best suited to your needs

Designs

There are three main categories of Defender®: mechanical, magnetic and electronic.

Mechanical Defenders®

Mechanical Defenders® are the most popular models. They feature a steel body and various protection mechanisms against break-in attempts by drilling, bumping and breaking the cylinder.

They represent the main defence for the cylinder and door security.
