DISEC BMAR05 – Security Locking Device for Door Handles
The DISEC BMAR05 is a mechanical handle locking device designed for compatible internal and external doors. Installed between the handle rose and the door, it prevents normal handle rotation until the release button is pressed. This version features a Ø52 mm circular body, an 8 mm square spindle opening and a polished brass finish.
How the handle lock works
The BMAR05 adds a security control to the existing door handle. When the mechanism is locked, the handle cannot be operated normally. To turn it, the user must press the mechanical release button while operating the handle.
This additional control helps resist attempts to operate the handle from outside through an opening made in the door. It provides supplementary protection and does not replace the existing door lock.

Compatibility and installation
The BMAR05 is designed for compatible handles with an 8 mm square spindle. It can be used on doors equipped with suitable patent or Yale-type lock configurations.
The device is fitted beneath the handle rose. Before ordering, check the rose diameter, available clearance, spindle length and fixing screws, allowing for the additional 5 mm thickness.
Important: the door handle is not included. Verify the 8 mm spindle and compatibility with the existing handle rose. This device does not replace the door lock or other security components. Contact Matteoda customer service for delivery information.
