The most prevalent closure system in Europe.
Effective in terms of safety and the small size of the key, the high security cylinder is protected from the outside by the “defender” that prevents the entry of burglary tools, unregistered keys, etc..
If properly fitted, SENTRY provides a noise reduction of 38 dB according to EN 140, and air tightness in class A2 according to EN 86.
Note: The noise reduction values are measured in the laboratory according to the above mentioned standards. The values measured during onsite installation may not reach similar values as a result of inferior performance or imperfections of the civil engineering works and installation.
Available in the single or double leaf versions.
The closure system is also available in the class 4 version.
