DK by security

Anti burglary system

The DK by security is a anti-intrusion system and it is always activated.

Unlike traditional window latches, with the DK system you cannot drill a hole in the window and use a hook to turn the handle and open a window from the outside.You open the window inside by pushing a button which unlocks the rotation block; then you can turn the handle.

The system is simple. This is also a child safety device, since smaller children cannot easily time perform two actions simultaneously.

It is quiet, discreet, and can be applied to all Olivari models. The security button can be assembled above or below as preferred.

DK is an Olivari patent.
