DISEC MG740 – 4W Magnetic Security Protector for Roller Shutters
The DISEC MG740 is a magnetic security protector for central roller shutter locks, intended for compatible shop shutters, garage doors and metal closures. Its 4W magnetic locking system controls a sliding cover that shields the lock's key opening. Steel construction with manganese reinforcement and a black finish.
Magnetic lock protection
The DISEC KM0P85 magnetic key releases the sliding cover, allowing access to the original lock key opening. When the cover is closed, it shields the lock from direct access.
The steel body and magnetic cover provide additional protection against tampering, attempted cylinder extraction and unauthorised manipulation. The MG740 is a supplementary security device and does not replace the existing shutter lock.
